海外TECH	DEV Community	reduce() method in javascript	https://dev.to/therajatg/reduce-method-in-javascript-138o	reduce method in javascriptLet s see what MDN has to say The reduce method executes a user supplied “reducer callback function on each element of the array in order passing in the return value from the calculation on the preceding element The final result of running the reducer across all elements of the array is a single value The first time that the callback is run there is no return value of the previous calculation If supplied an initial value may be used in its place Otherwise the array element at index is used as the initial value and iteration starts from the next element index instead of index pretty intense ️ Actually this one is quite tricky as compared to map and filter for now understand this Each element of the array passes through the function provided by us in order to give a single value as output The best way to understand is through examples So let s get the ball rolling Example Given an array of numbers return the sum of all numbers const numbersArray we ll understand using normal function function sum accumulator currentValue return acc current const output numbersArray reduce sum console log output Result So what the heck just happened Don t worry just listen to me carefully and while doing that refer to the above example Let s first try to understand this basic syntax of the reducer function reduce accumulator currentValue gt accumulator currentValue reducer function is the function that we define inside the reduce method This is the most important thing to understand If you get this the remaining blog will be a cakewalk for you accumulator The value resulting from the call to the reducer function The very first value of the accumulator is array currentValue The current element of the array The very first value of the currentValue is array currentValue is always the very next value of the one which the accumulator took in the previous step Still not clear Don t worry just go through the mental model of what happens when we call the sum function in the above example and everything will be crystal clear Step Since the very first value of the accumulator is array Hence in the above example it will be The very first value of the currentValue is array Hence in the above example it will be Step As per the instructions given in the sum function accumulator currentValue that is will be returned we got the values of both accumulator and currentValue from the above step Step The returned value from the above step that is will be stored in the accumulator for the next iteration and the currentValue will now be set to Step As per the instructions given in the sum function accumulator currentValue that is will be returned we got the values of both accumulator and currentValue from the above step Step The returned value from the above step that is will be stored in the accumulator for the next iteration and the currentValue will now be set to step As per the instructions given in the sum function accumulator currentValue that is will be returned we got the values of both accumulator and currentValue from the above step I hope you understood now how the basic version of reduce is working Let s do one more similar example Example Given an array of numbers return the multiplication of the numbers const numbersArray using arrow function const output numbersArray reduce acc current gt acc current console log output Result Understand the above example based on the mental model discussed above Now that you have understood the basic version of reduce let me introduce a little advanced version Here s the syntax reduce accumulator currentValue gt accumulator currentValue initialValue So what the heck is initialValue initialValue is the value to which our accumulator is initialized the first time the reducer function is called value Whenever the initialValue is provided the value of other variables changes Here s what changes when initialValue is present accumulator The very first value of the accumulator is the initialValue if it is specified currentValue The very first value of the currentValue is array if the initialValue is specified Not clear See the below example Example const numbersArray we ll understand using normal function function sum accumulator currentValue return acc current const output numbersArray reduce sum console log output Result Here ️ is the initial value Still not clear let s again understand via the mental model Step Since the very first value of the accumulator is equal to the initialValue Hence in the above example it will be The very first value of the currentValue this time is array Hence in the above example it will be Step As per the instructions given in the sum function accumulator currentValue that is will be returned we got the values of both accumulator and currentValue from the above step Step The returned value from the above step that is will be stored in the accumulator for the next iteration and the currentValue will now be set to Step As per the instructions given in the sum function accumulator currentValue that is will be returned we got the values of both accumulator and currentValue from the above step Step The returned value from the above step that is will be stored in the accumulator for the next iteration and the currentValue will now be set to step As per the instructions given in the sum function accumulator currentValue that is will be returned we got the values of both accumulator and currentValue from the above step Step The returned value from the above step that is will be stored in the accumulator for the next iteration and the currentValue will now be set to step As per the instructions given in the sum function accumulator currentValue that is will be returned we got the values of both accumulator and currentValue from the above step I hope you understood now how this version too MAN WRITING THIS BLOG IS TAKING TOO MUCH TIME But I have got to complete and you have got to understand Kill the choices and you ll be free sounds counterintuitive but it s not Let s do some more examples and I ll be using arrow functions only If you need the same solution to be written in terms of normal functions too tell me in the comments and I ll be happy to do it Example Given an array of numbers find the sum of all odd numbers const numbersArray const sumOdd numbersArray reduce acc current gt current acc acc current console log sumOdd Result In the above example for each iteration the value of the accumulator will remain the same if the number encountered is even However the previous value of the accumulator will be added to the currentValue to give us a new accumulator for the next iteration if the number is even The initialValue is Let s see another example to understand better Example Given an array of numbers filter out the highest value from the array const numbersArray const max numbersArray reduce acc current gt acc gt current acc current console log max Result Logic in the above example If accumulator is bigger than use the same accumulator for the next iteration and if currentValue is bigger use currentValue as an accumulator for the next iteration Here s one more example Example Return an object with the sum of odd and even numbers separately I want something like this to be returned evenSum oddSum Remember I told you that reduce only returns a single value Here s a fun fact that value can be an object const numbersArray const sumEvenOdd numbersArray reduce acc current gt current acc even acc even current acc odd acc odd current even odd console log sumEvenOdd Result even odd Some of you might be dumb like me and don t understand things instantly So here s a little explanation for my kind Note in the above example I used the spread operator acc if you don t understand what it is you may wanna read about it first Step The very first value of the accumulator will be set to even odd as this is the initialValue Step Now the first element of the array will be passed through the reducer function The reducer function will see if the currentValue is divisible by Since the currentValue is not divisible by the reducer function will return acc odd acc odd current which may seem complicated but it s just even odd that is even odd Step In this iteration the currentValue is that is even Hence the reducer will return even odd that is even odd Step In this iteration the currentValue is that is odd Hence the reducer will return even odd that is even odd Step and so on until we get even odd Now one more example and I promise this will be the last one If you have read my blog on filter I used the same example there and achieved the result using map and filter both Here we ll achieve the desired outcome using reduce only Remember I told you that reduce only returns a single value and the value can be an object Here s a fun fact that value can be an array too Example Given the below array const details firstName Rajat lastName Gupta age firstName Barack lastName Obama age firstName Elon lastName Musk age firstName Joe lastName Rogan age firstName Abdul lastName Kalam age Can you filter out the firstName of the persons having an age of more than console log details reduce acc current gt current age gt acc current firstName acc Result Barack Abdul Again for the people who are a little slow like me Here s a little explanation Note in the above example I used the spread operator acc if you don t understand what it is you may wanna read about it first Step The very first value of the accumulator will be set to an empty array Step Now the first element of the array that is an object will be passed through the reducer function The reducer function will see the age and if since the age is lesser than the value of the accumulator will remain the same for the next iteration accumulator Step In this iteration the age is greater than hence the accumulator s value will change to Barack Step The value of the accumulator will remain the same for the next iterations Step In this iteration the age is greater than hence the accumulator will change its value from Barack to Barack Abdul That s all folks If you have any doubt ask me in the comments section and I ll try to answer as soon as possible I write one article every day related to web development yes every single f cking day Follow me here if you are learning the same If you love the article follow me on

海外TECH	DEV Community	Mapping Earthquakes in the Permian Basin	https://dev.to/spara_50/mapping-earthquakes-in-the-permian-basin-2p0i	Mapping Earthquakes in the Permian BasinWhen I read an article about earthquakes caused by fracking in west Texas I wanted to map the data Additional research referenced a report published in Science Titled High rate injection is associated with the increase in U S mid continent seismicity the report provided data sources that I could use for the map Data sourcesI used the following data sources for the map Geologic UnitsGeologic FaultsOil and Gas WellsEarthquakesCounties Design ProcessBase map While a simple map of county boundaries gives the viewer a sense of location I wanted to show the underlying geology and structures Earthquakes occur in counties with sandstone a relatively stable geologic unit not prone to earthquakes Similarly faults are associated with earthquakes but are far from earthquakes Adding the major geologic units adds context to the map Wells Showing the distribution of wells in west Texas was an interesting problem One method to show the density of wells would be to aggregate the number of wells by county and color the counties in ascending order using a color ramp This method would be effective but it would occlude the geologic map Additionally the additional colors and the geologic units would be visually confusing I choose to use a heat map to display the distribution of wells I can overlay the well data with decreased opacity and display the underlying geologic units remain visible Earthquakes The earthquake data contains many records less than magnitude on the Richter scale I opted not to display the lesser magnitude earthquakes because they are typically not felt Earthquakes with a magnitude of to are often felt and might cause damage The Richter scale is logarithmic this quote explains ground motion at different magnitudes Magnitudes are based on a logarithmic scale base This means that for each whole number you go up on the magnitude scale the amplitude of the ground motion recorded by a seismograph goes up ten times Using this scale a magnitude earthquake would result in ten times the level of ground shaking as a magnitude earthquake and about times as much energy would be released To give you an idea of how these numbers can add up think of it in terms of the energy released by explosives a magnitude seismic wave releases as much energy as blowing up ounces of TNT A magnitude earthquake releases as much energy as detonating million tons of TNT Pretty impressive huh Fortunately most of the earthquakes that occur each year are much too small to be felt by most people I choose different geometric shapes and colors to represent earthquakes of different magnitude Because I wanted to convey the difference in ground motion the marker size becomes progressively larger as the magnitude increases The different shapes colors and sizes also help reduce visual clutter Cartographic ProcessI used QGIS to prototype the map The data was in various formats ranging from geodatabases shapefiles and CSV files In addition the data was in different projections QGIS is handy for reading different data formats and reprojecting them into a standard projection It also has a good set of tools for manipulating data and tools for styling The USGS provides a qml style file file which is how QGIS saves style information Unfortunately the USGS qml file is an older format that is unsupported by the current version of QGIS I had to rebuild the styles from the USGS qml file manually Tedious but not terrible In addition I used the heatmap style to show the distribution of wells This makes for a striking image but I ll discuss why this was not the best choice in the follow up post Here s the final map styled using QGIS Next StepsThe map rendering is complicated and implementing it would take some time as a web map I ll show how to deploy the map as a static web application in the following post	2022-02-18 19:37:10

海外TECH	DEV Community	Designing a Typewriter React Component	https://dev.to/shivishbrahma/designing-a-typewriter-react-component-3kea	Designing a Typewriter React ComponentWe are pretty much familiar with the Typewriter effect although we might not be acquainted with a Typewriter In words the typewriter effect is the gradual revealing of the words as if it is being typed infront of our eyes with sound of a typewriter key pressing A popular Typewriter Animation in Web usually involves slowling revealing of the text with a blinking cursor and slowling erasing of the text with a pause Though in our today s exercise we will be implementing a typewriter effect where a list of words are being typed on the screen with a blinking caret or cursor After each word is being typed it s also erased after a little pause to erase slowly one letter at a time and finally typed in for the next word Getting StartedWe won t require no extra libraries except the ones installed by create react app template Typewriter jsximport React from react function Typewriter text otherProps return lt div className Typewriter otherProps gt lt span className Typewriter text gt text lt span gt lt span className Typewriter cursor gt lt span gt lt div gt export default Typewriter A classic functional component that has text string prop for content and two child components i e typewriter text and typewriter cursor Implementation Blinking caretTo design the blinking caret we will need css into action Typewriter css Typewriter text display inline block Typewriter cursor display inline block color currentColor animation blink s ease in out s infinite alternate keyframes blink from opacity to opacity CSS Animations is used for blinking and both child components are made inline block for making them side by side Add a import in Typewriter jsx after React importimport React from react import Typewriter css Typing EffectWe will use two React Hooks namely useState and useEffect for this purpose function Typewriter text speed otherProps const currentText setCurrentText React useState const timeout set Timeout React useState null React useEffect gt startTyping return gt timeout amp amp clearTimeout timeout React useEffect gt let rawText text if currentText length lt rawText length set Timeout setTimeout type speed return gt timeout amp amp clearTimeout timeout currentText function

return lt div className Typewriter otherProps gt lt span className Typewriter text gt currentText lt span gt lt span className Typewriter cursor gt lt span gt lt div gt The function startTyping initiates the first call for text change The function type updates the current text while on every update of currentText type function is called after every speed which is passed as a prop milliseconds Erasing EffectWe have already implemented the typing effect and for erasing effect we need a flag to know whether we are typing or erasing Thereby we can create a cycle of typing to erasing and vice versa function Typewriter text speed eraseSpeed typingDelay eraseDelay otherProps const isTyping setIsTyping React useState true React useEffect gt let rawText text if isTyping if

startTyping when currentText length is zero with typingDelay added to the props seconds and switch to typing else erase is called after every eraseSpeed added to the props milliseconds For typing mode added switch to erasing after erasingDelay when currentText length reaches full length Enabling Array of TextWe need to add an index for the array and function to handle array or string for text prop

currentText substr currentText length currentText length setCurrentText displayText else const textArray getRawText index index textArray length index setCurrentIndex index Added getRawText function to handle string or array at the same time from text prop and added state variable currentIndex for array index Updated useEffect for currentText in erasing mode to switch to next string in array and

海外TECH	DEV Community	The Importance of Vision as a Developer	https://dev.to/dangoslen/the-importance-of-vision-as-a-developer-d6n	The Importance of Vision as a DeveloperFixer Upper We all love it Even if you hate it…you still kinda love it If you are unfamiliar with the show living under a rock Chip and Joanna Gaines help prospective homeowners build their dream homes by finding cheaper “fixer upper homes and remodeling them saving the homebuyer s money The process is called house flipping and it has become an enormous phenomenon especially here in the US But how can someone take a house in shambles and turn it into a dream home How do they avoid getting stuck while remodeling and throwing in the towel Many qualities are required persistence skill sacrifice etc But there is one quality that is neccesary One thing that is the predictor for success or failure That difference is vision What is Vision Simply put pision is the ability to see In the creative context vision is the ability to see how things could be The ability to grasp a different perspective unique to everyone else The ability to imagine a different world than the current reality This is why we call visionaries well visionary They can envision things no one else can And the household names we remember are the ones who had vision and the ability to bring it to fruition Bell Edison Earheart Jobs etc But it all starts with vision Why is Vision So Important Why is vision so important Isn t it just the same as having a goal or plan I d argue that true vision comes before creating goals or laying out a plan Vision is something more significant A vision says “We can do something different We can change how the world works We don t have to accept the status quo A strong vision is more immersive than a goal or a plan It might be so grand that a single goal can t contain it It might be so hard to articulate that no plan seems to accommodate all of the complexity to make it happen A vision is more like a guidebook helping you choose plans steps and goals to realize the vision you have Many successful athletes and actors talk about picturing themselves getting the medal or landing the role Climbers or runners describe what it will feel like to send the summit or cross the finish line House flippers and creatives can talk about the potential they see in an old house or a blank canvas in exquisite detail Vision like this acts as both a direction and a motivator It sets the course for where you are going and provides enough tangibility to something distant in the future to keep you motivated Vision in DevelopmentIf that sounds like a bit of mumble jumbo self help garbage to you stay with me just a little bit longer Vision isn t just about achieving your dreams of changing the world It s also crucial for building anything significant or complex like software Let s go back to house flipping for a second If you bought a house with the goal of flipping it for profit you might get stuck halfway confused about what to do how to do it and what direction to focus your energy You might have been so focused on the goal of making money that you forgot to see what was possible and if it would be profitable Even if you did have a thought out detailed plan you might run into a roadblock and realize that your perfect plan wasn t so perfect after all But vision is different Bringing a vision to fruition can still be possible even if the concrete plan changes frequently In software vision is critical for that exact reason plans and goals can change quickly but we still need a motivator for technical excellence and a direction to march towards An excellent technical vision describes how developers feel when writing code and the ease with which they can monitor their software It explains how teams work together and the breadcrumbs they leave along the way to make the path clear for the next team How people feel working on the engineering team and how they feel supported by management might be included too Vision can also be micro A senior engineer might have a vision for how a particular codebase is organized They might describe the reliability of their service or how easy it is to be on call for that service because it rarely goes down They might even discuss the throughput they think is possible to supercharge the business Creating a VisionIf you re still here the next logical question is of course how do you create a vision While there is a lot to explore in the answer much of which can t be covered in this article there are a few key things to cover The most important aspect is found in answering two primary questions What will the future feel like when your vision is achieved How will things be different from today Be as detailed as possible Don t say “Work will be easier Say “Work will be easier to accomplish because our codebase is easy to understand and we have tests to identify when we ve broken functionality When you have this level of detail it paints a more vivid and clear picture of where you want to go A stick figure picture of a mountain is much less compelling than a painting of a mountain with color and dimension Create the painting Gaining Buy inThe hardest part of a vision is articulating it to others to gain buy in You will likely need their support especially in the world of software where teams own software and not individuals How do you gain that buy in The power comes from being able to articulate the vision in your head in a compelling way to others This is another reason why having an extremely clear vision is so important The more detailed and clear your vision is the easier it will be to describe to others Naturally some will disagree with your vision Others might hear it and be impartial they don t hate it but they don t like it either But other will get it and buy in As more buy in it becomes easier to gain more since everyone wants to be part of a movement of some kind even if it s small Keep talking to your team or fellow leaders about how you think things can be different how your vision can take your team to the next level Practice humility of course but don t be shy either As Andy Hunt and Dave Thomas remind us in Pragmatic Programmers the best idea is worthless if no one knows about it Building great software and great teams requires a vision for the future One that elevates the current reality into a better one And while goals and plans are great having a foundational vision of what that world looks like in the future will help you stay motivated navigate changes and create buy in along the way If you are a leader or becoming one in your software team take an inventory of the current work environment Take a look at how teams operate and how work flows through your organization Identify a few things that could be better and imagine what it would be like if none of those issues existed anymore What would that world be like Write it down

海外TECH	DEV Community	Copy by Value vs Reference	https://dev.to/iamgjert/copy-by-value-vs-reference-1bd3	Copy by Value vs ReferenceIntroThere are two ways to pass a value to a variable in JavaScript and understanding how they operate is fundamental to your success at manipulating data in your code In this short blog I will explain the differences between the two and provide examples along the way Variables will either be passed a copy of the value of they re being assigned or be passed a reference to the value they re being assigned Copy by ValueWhen working with primitive data types numbers strings Booleans null and undefined your variables will be making a copy of the value they re being assigned and represent that specific copy of the value Any changes to the original data will not effect the copy that was made and stored in the variable we ve created Vice versa these values stored into our variable can be manipulated without any changes to the original data In the image above b is being assigned the value stored in the a variable Since the a variable is storing a primitive data type b is assigned a copy of that value Any changes made to a later on will not effect b s value a true b truea undefined console log b prints not effected by a being reassigned Copy by ReferenceWhen working with complex data types Objects arrays functions your variables will not make a copy of the value they re being assigned to but instead will make a reference to that data Any manipulation of our variable will effect the original data since our variable is just a reference to the original data Similarly any changes to the original data will effect our variable as well let a name Object color blue let b a In the code above the a variable has been assigned to an object with two properties Just under that we ve assigned the b variable to the a variable When the b variable is assigned here it will be assigned a reference to the same object the a variable is already assigned to Any changes to the b variable will effect the original data stored in the a variable b color orange Since both variables point to the same object the color of the object both variables point to will be assigned to orange console log a prints name Object color orange console log b prints name Object color orange In SummaryIt s important to know whether the data you re working with is a copy or a reference If you re working with a copy it s less detrimental to the overall program as your changes are localized to that copy of the data When working with a reference your changes effect the overall data and can produce unwanted changes later in your code if not caught	2022-02-18 19:15:30

海外TECH	Engadget	‘Uncharted’ boldly goes nowhere	https://www.engadget.com/uncharted-movie-review-tom-holland-mark-wahlberg-190043901.html?src=rss	Uncharted boldly goes nowhereThere are worse movies than Uncharted especially when it comes to the seemingly cursed genre of video game adaptations But as I struggled to stay awake through the finale ーyet another weightless action sequence where our heroes quip defy physics and never feel like they re in any genuine danger ーI couldn t help but wonder why the film was so aggressively average Sony PicturesThe PlayStation franchise started out as a Tomb Raider clone starring a dude who wasn t Indiana Jones But starting with Uncharted Among Thieves the games tapped into the language of action movies to put you in the center of innovative set pieces They were cinematic in ways that few titles were in the early s But going in the opposite direction ーbringing aspects of those games into a movie ーdoesn t work nearly as well Director Ruben Fleischer Zombieland Venom along with screenwriters Rafe Lee Judkins Art Marcum and Matt Holloway have crafted an origin story for the treasure hunter Nathan Drake Tom Holland It hits the notes you re expecting ーhis childhood as an orphan his first team up with his partner Victor quot Sully quot Sullivan Mark Wahlberg and a globe trotting treasure hunt that defies logic ーbut it s all just a Cliff s Notes version of what we ve seen in the games And for a franchise that was already a watered down version of Indiana Jones a movie adaptation just highlights all of its inherent flaws Watching Uncharted made me long for the basic pleasures of Nicholas Cage s National Treasure at least that Indy clone had personality Even the iconic action scenes don t hit as hard The film opens mid free fall as Drake realizes he just fell out of a plane Discerning viewers will instantly recognize the sequence from Uncharted We watch as he hops across falling cargo and wonder if that s even possible while everything is falling but the entire scene feels like Tom Holland is going on the world s most extreme Disney World ride Without the rumble of the Dualshock controller in my hand and my responsibility over Drake s impending death there just aren t any stakes It s particularly unexciting compared to what we ve seen in the recent Mission Impossible movies Tom Cruise and skydiving camera man Craig O Brien jumped out of an actual plane several times for our entertainment Still it s somewhat surprising that this adaptation exists at all Sony has been trying to develop an Uncharted film since starting with a loftier iteration by arthouse auteur David O Russell That version was going to star Wahlberg as an older Nathan Drake as we see him in the games and focus on the idea of family But the project ended up changing hands several times over the last decade By the time it was actually gearing up for production in Wahlberg had aged out of the starring role and into the older sidekick spot Sorry Super Cool Mack Daddy it happens to all of us After we ve seen so many video game films completely miss the mark like Resident Evil Welcome to Racoon City and Assassin s Creed I m starting to wonder if there s some sort of secret to making a good adaptation Different audiences want different things after all Game fans typically want to see the characters and sequences they love so much legitimized on film Discerning movie geeks may be comparing adaptations to other usually better films And studio executives just want existing intellectual property that they can churn out to an undiscerning public There are a handful of memorable video game films but they mostly seem like flukes The original Mortal Kombat was iconic because of its killer soundtrack and at the time cutting edge special effects Werewolves Within doesn t have much to do with the VR title it s based on aside from its name And Sonic the Hedgehog was a blast but that was mostly due to its lead performances nbsp nbsp As an avid gamer and cinephile I ll never give up on hoping for successful adaptations But it could just be that the two mediums are a bit incompatible A film can never capture the interactive magic and freedom you get from a game And when you re playing something heavy handed cut scenes and direction can often take you out of the experience unless you re Hideo Kojima in which case gamers will argue it s all a work of genius With its cinematic roots Uncharted had a better shot at a decent adaptation than most games It s just a shame that for a series that s about exploring new lands and discovering forgotten treasure it offers nothing new	2022-02-18 19:00:43
