海外TECH	DEV Community	Loops in Javascript	https://dev.to/shubhamtiwari909/loops-in-javascript-2g9g	Loops in JavascriptHello guys Today i am going to discuss Loops in javascriptWhat is a loop Loops can execute a block of code a number of times until a given condition returns false and the loop breaks Loops are handy if you want to run the same code over and over again each time with a different value Example Suppose we have an array const cars BMW Volvo Saab Ford Fiat Audi We want to print the element of this array So Instead of writing text cars lt br gt text cars lt br gt text cars lt br gt text cars lt br gt text cars lt br gt text cars lt br gt You can write for let i i lt cars length i text cars i lt br gt Output BMWVolvoSaabFordFiatAudiDifferent Kinds of Loops JavaScript supports different kinds of loops for loops through a block of code a number of timesfor in loops through the properties of an objectfor of loops through the values of an iterable objectwhile loops through a block of code while a specified condition is truedo while also loops through a block of code while a specified condition is trueThe For Loop The for loop has the following syntax for initialization condition increment decrement code block to be executed initialization The initial value of the loopcondition To check that the condition is satisfied or not to come out of the loopincrement decrement To increase or decrese the value and get to the next iteration Example for let i i lt i text The number is i lt br gt Output The number is The number is The number is The number is The number is From the example above you can read Statement sets a variable before the loop starts let i Statement defines the condition for the loop to run i must be less than Statement increases a value i each time the code block in the loop has been executed The For In Loop The JavaScript for in statement loops through the properties of an ObjectSyntaxfor key in object code block to be executed Example const person fname John lname Doe age let text for let x in person text person x Output John Doe Example ExplainedThe for in loop iterates over a person objectEach iteration returns a key x The key is used to access the value of the keyThe value of the key is person x The For Of Loop The JavaScript for of statement loops through the values of an iterable object It lets you loop over iterable data structures such as Arrays Strings Maps NodeLists and more Syntaxfor variable of iterable code block to be executed variable For every iteration the value of the next property is assigned to the variable Variable can be declared with const let or var iterable An object that has iterable properties Example const cars BMW Volvo Mini let text for let x of cars text x Output BMWVolvoMiniThe While Loop The while loop loops through a block of code as long as a specified condition is true Syntaxwhile condition code block to be executed ExampleIn the following example the code in the loop will run over and over again as long as a variable i is less than while i lt text The number is i i Output The number is The number is The number is The number is The number is The number is The number is The number is The number is The number is NOTE If you forget to increase the variable used in the condition the loop will never end This will crash your browser Do While Loop The do while loop is a variant of the while loop This loop will execute the code block once before checking if the condition is true then it will repeat the loop as long as the condition is true Syntaxdo code block to be executed while condition ExampleThe example below uses a do while loop The loop will always be executed at least once even if the condition is false because the code block is executed before the condition is tested do text The number is i i while i lt Output The number is The number is The number is The number is The number is The number is The number is The number is The number is The number is Array forEach The forEach method calls a function a callback function once for each array element Example const numbers let txt numbers forEach myFunction function myFunction value index array txt value Output Note that the function takes arguments The item valueThe item indexThe array itselfThe example above uses only the value parameter It can be rewritten to const numbers let txt numbers forEach myFunction function myFunction value txt value THANK YOU FOR READING THIS POST AND IF YOU WANT TO GIVE ANY SUGGESTION OR FIND ANY ERROR PLEASE MENTION IT IN THE COMMENT SECTIONSOURCE	2021-12-02 17:41:26
海外TECH	DEV Community	A practical, step-by-step guide to using Chrome's DevTools	https://dev.to/khsheehan/a-practical-step-by-step-guide-to-using-chromes-devtools-4dam	A practical step by step guide to using Chrome x s DevTools IntroductionIn this post we ll aim to cover practical techniques developers can use to debug manipulate and otherwise probe running web applications via Chrome s built in devtools The goal is to articulate the specific steps and shortcuts we would use at Reflect and to favor breadth over depth Readers can follow the guide step by step and try it out themselves at the provided link provided below With that in mind let s imagine the following contrived scenario You are an engineer recently put in charge of leading your organization s webapp development You have relatively little experience with the codebase and the last person who was in charge has since left A support ticket comes in from a frustrated user complaining that a specific page in your app is slow There is no additional context and there have been no deployments for a week Rather than jumping right into your editor and trying to aimlessly solve the problem there let s instead use devtools to begin the investigation Demo amp WalkthroughLet s assume you or your team has already looked at the health of the services APIs that power the app and everything looks good It appears that the issue reported by the user is isolated to the frontend itself The first thing we d like to do is just load the page and see if anything jumps out at us All we know is that the user complained that the app is slow Step Open the link below in a new tab window and confirm it loadsWalkthrough LinkThe page in question has very little going on A single image and some scrollable text Intuitively a few things stand out The first is that when the user says the app is slow they likely mean one of two thingsThe text and image are slow to load You ve already counted this out by inspecting the network and confirming pages load quicklyThe text jitters while being scrolled and leads to a janky experienceYou try scrolling the text and observe that it s smooth Now what We ve taken some time to inspect the page visually and cannot repro the reported experience ourselves Let s open devtools and start poking around under the hood Step Use cmd alt i on mac to open devtools Ensure you are on the Elements panel Note The rest of this article assumes your devtools are docked to the right side of the page and that they are wide enough to position subpanels side by side Let s start by taking a closer look at the image on the page Step Open the console at bottom of devtools by pressing the esc keyWe want to grab the image element and log it to the console We could use document querySelector img to find it but in this case we can instead use the globally defined function This function is built into devtools and will work as a shorthand for document querySelector as long as the underlying application does not overwrite it e g if the app loaded jquery then would be overwritten Step Find the element with img The element is now logged in the console and we want to inspect it in the DOM itself Step Right click the element in the console and select Reveal in Elements panel Notice the tiny inline next to the element in the Elements panel This indicates that the element has been assigned to the global variable Step Confirm this is the case by typing then enter in the console Observe that the element has been logged againWe ll now start investigating this element and look for any red flags Remember that we have nothing to go on beyond the single support ticket Looking at the styles attached to this element nothing in particular stands out Note The styles seem a bit odd given what they actually achieve but we ll ignore this for the sake of the demo After inspecting the styles let s see if there is any javascript based functionality attached to this element Step In the top right of the Elements panel select the Event Listeners tab It may be hidden behind a gt gt button Alright We ve identified that there s an event listener bound to this element that we weren t aware of before In this case it s some functionality bound to the click event Let s try clicking on the image and see what happens Nothing That s odd we expect something to happen when a user clicks based on the click event listener we found in the Event Listeners tab Let s take a closer look at exactly what was supposed to happen Step Expand the click event and observe the link to the listener s source Click it Devtools has now brought us to the Sources panel and specifically to the line in our application that defines the listener Taking a closer look we see that the behavior on click is conditional based on whether or not the user was holding the shift key const onKeyUp e gt if e shiftKey img classList add fun animation Now that we better understand the source we can try it out ourselves We want to verify that the listener is definitely executing when the user holds shift and clicks A good approximation for this would be to just try it out ourselves but we can be more certain if we use the debugger Step Right click on the first line of the conditional in the listener and add a conditional breakpoint of e shiftKeyNow hold shift and click the image You ll observe that execution was paused at our breakpoint and we re definitely going to execute the listener Remove the breakpoint by clicking on the orange line marker and click the Resume execution button in the top right Bad Performance Alert Not only have we figured out a way to trigger the functionality attached to the element but we ve just seen our first big red flag CSS animations are one of many very common performance pitfalls We haven t yet figured out exactly what the problem is but this is a great direction to focus in on Note You ve now spoken to your manager and confirmed it is absolutely essential to the business that this image animates under these conditions and it animates precisely the way it s written Sorry We can t ourselves observe any obvious performance issues but that may be because you re working on a much more powerful machine than the user who reported the slowness We can t assume that the issue does not repro or is not caused by the animation just because we can t experience it firsthand We have tools that allow us to measure performance Step Reload the page with cmd r so we re back in the original state Open the performance panel in the top row of devtools and begin recording for about seconds Then trigger the animation with shift click wait another seconds then finish the recording If the graph is too short to see you can once again close the console by pressing escJackpot The performance panel is telling us that we have a serious problem with layout shift We won t cover this topic in depth in this article just know that Layout is one of the steps in the rendering pipeline and is responsible for computing where every node on the page will ultimately be rendered and at what size Because all nodes in the DOM can affect the position size of all other nodes this process is complicated and we want to keep layout shift to a minimum Our goal now is to identify why precisely these layout shift events are constantly firing and to figure out a way to minimize or remove them entirely while preserving the animation Let s jump into the Layers panel to get a better sense of how the renderer sees the page Step Press cmd shift p to bring up the Command Menu and start typing layers Press enter when Show Layers is highlighted I also suggest checking the Paints checkbox to see the pixels that are being rendered Note The command menu acts as a shortcut to many of the most common actions you d take in devtools It is one of the best optimizations in devtools and can be used to change settings switch panels and more Play with it We re now on the Layers panel If you ve never seen this before don t worry there s not much we need to understand in order to use it in this example The critical piece of information to know is that this is essentially a D model of the way our application is layered from the rendering pipeline s perspective When the browser rasterizes the parts of the page into pixels at the compositing stage these D layers will be rendered onto the D plane of the viewport The Layers panel isn t particularly interesting looking in its current state All we see is a big rectangle that represents our page But this is actually a clue to where the layout shift is coming from When the image is animating changing dimensions it is on the same layer as everything else in the browser This means that any changes to the image must result in the browser recalculating the layout of the entire document constantly You can observe that everything is on a single layer by pressing v to enter rotate mode then clicking and dragging the layers to rotate them in D space You ll see that the image is rendered on the base layer along with the text that does not scroll Based on what we observe on the page there s no reason why the image should not be on its own layer If it were lifted above the rest of the document then any changes to its dimensions will by definition have no layout impact on the rest of the document The image and the document should be modeled as completely distinct entities allowing one to change without impacting the other But hold on The browser is reporting that there s a constant layout shift occurring but we re not certain what specifically is shifting The text on the page doesn t appear to move so it s possible something else Let s try and identify where this layout shift is happening Step Press cmd shift p to bring up the Command Menu and start typing layout shift Press enter when Show layout shift regions is highlightedWe found it There s a region next to the image that is constantly having its layout shifted If you take a look at the DOM in the Elements panel you ll find a single div with nothing but a blank space in it lt div id tracking gt amp nbsp lt div gt Problem solved You could just remove that div and the layout shifts will go away There are two problems with this approach It does not solve for the issue originally discovered in the Layers panel That s the marketing team s tracking lt div gt Yes it s used in a webapp in the middle of a document and yes it s a div for some reason and no you can t move it So our goal is still the same We want to move the lt img gt onto its own layer so that the animation does not cause any layout shift There are a few ways to do this but for the sake of this article we ll use a specific positioning strategy we know will force the element onto its own layer When an element uses fixed positioning it is generally taken out of the normal flow of the document and positioned relative to the viewport itself This forces the element onto its own layer and thus hopefully solves the problem Let s try this out Step Inspect the lt img gt element again in the Elements panel You can use the technique described in Step or use the inspect element button in the top left of devtools then switch to the Styles tab Step Replace the position relative style with position fixed Step Now navigate to the Layers panel and expand the first item in the sidebar Observe there is now an img layer You can further confirm this layer is distinct by rotating the model and observing a separate layer for the image Step Navigate back to the performance tab record for seconds shift click the image wait for more seconds then stop recordingCongratulations The change you made to the positioning strategy forced the element onto its own layer which in turn meant that it has no layout impact on the rest of the document You can observe that the latest performance recording shows no more layout shifts happening ConclusionUsing only devtools we were able to identify the root cause and fix for a performance issue in a codebase with which we were not familiar Keep these tips in mind the next time you re trying to debug an application and keep in mind that devtools the browser itself are extensions of a webapp development environment like being part of an IDE Recapcmd alt i opens devtoolsesc will toggle a drawer containing the Console and other tools across all panels is shorthand for document querySelector assuming the page has not defined itself You can right click elements in the console and reveal them in the Elements panel is a global variable referring to the currently selected element in the Elements panelYou can set conditional breakpoints in the Sources panel by right clicking on a lineThe Layers panel gives you insights into how the renderer sees your application before compositingcmd shift p opens the Command Menu and can be used as a shortcut for most devtools actions CaveatThe example used in this article is contrived for simplicity and the performance issues would be better solved using other techniques like only allowing css transformations on styles that can be accelerated by the GPU The goal is to show the reader devtools techniques with applications in the real world not to espouse the actual code writing skills needed to build a performant application	2021-12-02 17:32:50
海外TECH	DEV Community	Add flying emoji reactions to a React video chat app	https://dev.to/trydaily/add-flying-emoji-reactions-to-a-react-video-chat-app-5hma	Add flying emoji reactions to a React video chat appIf a picture is worth a thousand words what does that mean for emoji For decades they ve been used to add color to all sorts of written communications from text messages to entire translations of Moby Dick to ーmost relevant to this blog post ーvideo calls We build developer tools at Daily that enable new ways to communicate online Adding emoji reactions to video chats gives participants a familiar and fun way to express themselves In this tutorial we ll add a set of flying emoji reactions to a custom video call built on the Daily call object To achieve this we will Create a button that sends an emoji of our choice flying on click Send our emoji reaction to all other participants using the Daily sendAppMessage methodRender the emoji for both the local participant who sent it and the remote participants who receive it We will do all of these things in a Next js demo app that we built in a previous post Reference that tutorial for details on the foundation of the app like participant device and track management This post just focuses on the emoji The demo and code snippets are React based but you can still apply the essence of the steps outlined in the tutorial to work with other frameworks To run the demo locally Fork and clone the daily demos examples repository cd examples custom flying emojis Set your DAILY API KEY and DAILY DOMAIN env variables see env example yarn yarn workspace custom flying emojis dev With that our emoji are ready to fly Create a button that sends an emoji flyingThe star icon labeled Emoji in the call tray component Tray js reveals

handleReceiveFlyingEmoji passes the message data from e data message along to handleDisplayFlyingEmoji Render the emoji for both the local sender and the remote recipienthandleDisplayFlyingEmoji is called both on sending in handleSendFlyingEmoji and upon receiving in handleReceiveFlyingEmoji That s because app message only fires for remote participants but we want the local participant to see their own emoji reaction as well The handleDisplayFlyingEmoji function takes a string as a parameter handleSendFlyingEmoji passes the display handler a string from the CustomEvent detail from the window event while handleReceiveFlyingEmoji passes a string from the app message event object e data message Now that we know how and when handleDisplayFlyingEmoji is executed let s have a look at its

海外TECH	DEV Community	Debugging Multer and other middle-wares	https://dev.to/bacloud14/debugging-multer-and-other-middle-wares-3d2	Debugging Multer and other middle waresI ve been sipping coffee rolling cigarettes and pulling my hair since the day before yesterday I have trouble setting what I thought a useful dynamic middle ware for later implementations Post request with so much constraints now and surely in future The issue is with Multer or connect sequence see later If you know Multer is a Node js middleware for handling including parsing multipart form data What I expect could differ though and this is why I m setting this super intelligent middle ware I found how to chain middle wares on runtime which is not a very usual task but possible and very useful for my case connect sequenceThe solution dates a bit as you can see Anyway here is a slice of my middle ware code that constructs and runs other middle wares in return async function magicMiddleware req res next const contentType req get content type const form formidable if contentType indexOf multipart form data gt await form parse req function err fields files if err console log String err return magicMiddleware fields else magicMiddleware req const section req params const method req method const magicMiddleware body gt const secured upload geolocation illustrations schema constraints process env NODE ENV method section singletonSchema schema Third party middlewares var seq new ConnectSequence req res next debugger const validating celebrate Segments BODY singletonSchema if upload console log attaching multer seq append ops multer if singletonSchema called seq append validating seq append errors if secured console log attaching multer seq append ops auth seq run console log req body It is to know that third party middle wares could mismatch One adds something to req and one remove the same thing for instance I run debugger and couldn t find out but I think multer specifically is not running well It is running but not well req body is not undefined and not anything else I put multer at first in the sequence to be able to parse multipart form data data I m testing right now then there is celebrate Joi based validation middle ware Then there is auth too for passwordless authentication Of course there are multiple application middle ware attached when the app starts But none is susceptible of causing harm as if I push multer celebrate and auth as middle wares directly as usual all works fine So data is parsed req body is there with the uploaded file and input text fields I m pulling my hair really As I don t want to cancel all this and start from zero pushing middle wares directly on multiple post requests with different constraints like one runs without authentication the other expects text plain all combinations might behave differently on different environments like no upload when testing with Postman If you have a hint I will follow up with test If you want to jump on code here is the file and here is the repo Note there is a bug in connect sequence It is expecting err passed through next err to be different that undefined But Multer appears to push null when there is no error So there is this I modified code accordingly From this if err undefined To this if err Final note I want to believe in in connect sequence as I couldn t find my way adding middle wares at runtime I went through code not debugging and all seems well to my eyes Thanks a lot	2021-12-02 17:11:43
