海外TECH	DEV Community	🎨 Understanding the CSS rgb model (Visualized)	https://dev.to/babib/understanding-the-css-rgb-model-visualized-317a	Understanding the CSS rgb model Visualized The RGB model is an additive color model where the colors red green and blue can be added together in different intensities to form a wide array of colors The additive colors start with black then adds red green and blue With the rgb function the arguments are used to produce colorEach argument red green blue can range from to O means there is of that color and means there is of that color For example We ll use div elements to demonstrate the use of the rgb model lt div class markers gt lt div class strip one gt lt div gt lt div class strip two gt lt div gt lt div class strip three gt lt div gt lt div gt markers padding px strip width px height px margin px auto Now using the rgb concept explained above we could set the background colors of strip and to the different primary colors red green and blue respectively one background color rgb two background color rgb three background color rgb OutputThe intensities of each color can be varied between and to get different shades For example to get a more natural color for green the second strip it s intensity could be reduced to half way between and two background color rgb OutputIncreasing the value of the color increases its brightness Red blue and green are primary colors so when they are added together in the highest intensities they form white white background color rgb And the total absence of all give black black background color rgb Secondary colorsSecondary colors are formed from the combination of two primary colors There are secondary colors YellowYellow is formed from the combination of pure red and pure green one background color rgb CyanCyan is formed from the combination of pure green and pure blue two background color rgb MagentaMagenta is formed from the combination of pure blue and pure red three background color rgb Output Tertiary ColorsTertiary colors are formed from a combination of a primary color and a nearby secondary color There are six tertiary colors OrangeOrange is formed from the combination of pure red and yellow and falls between the two on the color wheel Set red at max and green to one background color rgb Output Spring GreenSpring green is formed from the combination of pure green and cyan Set green to and blue to one background color rgb Output VioletViolet is formed from the combination of pure blue and magenta Set blue to and red to one background color rgb Output Chartreuse greenFormed from the combination of pure green and yellow Set green to and red to one background color rgb Output AzureFormed from the combination of pure blue and cyan Set blue to and green to one background color rgb Output RoseFormed from the combination of pure red and magenta Set red to and blue to one background color rgb OutputThanks for reading Now can you remember the combination for chartreuse green be honest header pic Katie Rainbow	2022-07-04 09:23:58
海外TECH	DEV Community	JavaScript generators ELI5	https://dev.to/pramit_marattha/javascript-generators-eli5-2o61	JavaScript generators ELIJavaScript generators are one of the most misunderstood and complicated concepts in JavaScript because most people don t see the value in them but bare in mind that this subject is actually quite useful JavaScript generators first appeared in the ES ECMAScript version of the JavaScript language A generator in its most basic definition is a process that can yield multiple different values and can be paused and resumed again In JavaScript a generator is made up of a generator function that produces an iterable Generator object In addition generators are able to handle unlimited data streams and can maintain state which makes it possible to create iterators efficiently Additionally when used in conjunction with promises generators can replicate the async await capabilities enabling us to interact with asynchronous code in a more direct and legible way Although async await is more frequently used to handle typical straightforward concurrent use cases such as getting data from an Application programming Interface API so on and so forth generators offers more sophisticated features that make it simple to actually develop and utilize it Let s first look at the distinctions between generator functions and normal functions before moving on to this particular subject In this article we ll learn everything there is to know about JavaScript generators including how to create generator functions iterate over Generator objects differentiate between yield and return within a generator and a variety of other features and aspects that generators offer We ll also learn why and where to use generators as well as why and where they are important So without further ado let s get started by first creating a very basic generators function script jsfunction thisIsGenerator yield yield yield yield yield The code above may have seemed a little strange to you and may have puzzled you because it is so peculiar and different from typical JavaScript The asterisks symbol next to the Keyword function may be the first unusual thing you notice The asterisks are solely used to indicate to JavaScript that this is a generator function Note This generator function name is just that ーa function name so you can give it whatever name you like There are no rules or restrictions As you can see there are five different yield statements inside the generator function We initially yield the first one then second and so on so forth Yield is essentially similar to a special kind of return keyword that can only be used inside of a generator This is because a generator s main goal is to execute some code return a value run more code return another value and so on until all the code inside of the generator has been successfully executed To use a generator we must first run the generator function which will give us an object called a generator object which we can use to manipulate the generator we just created To do this we must first obtain the generator object and execute the generator function which will give us the generator object script jsfunction thisIsGenerator yield yield yield yield yield const genObj thisIsGenerator console log genObj The code shown above will just log out and provide output that resembles something like this As you can see it is a bit complicated difficult to understand what is actually happening behind the scenes because so many different things are being shown to us but if you expand the prototypes you will notice that there are three main important functions next return and throw Next MethodThe next method is the only one we are concerned with at the moment In essence this method enables us to run the code inside of our generator So for instance if we call our genObj with the next function it will just return an object with value set to and done set to false script jsfunction thisIsGenerator yield yield yield yield yield const genObj thisIsGenerator const nextGenObj genObj next console log nextGenObj value done false OutputIt s crucial to keep in mind that every generator has two properties a value and a done one The done property will always be a Boolean value with the values true or false where true indicates that there is no more code to run and false indicates that there is Also keep in mind that the value will always be whatever is yielded Note The first time you run the generator all it does is construct an object called the generator object which you can then use to execute all of the code inside of it individually using its next property Therefore when we executed genObj next all the code inside of our generator was executed up until the first yield which in our instance was Thereafter the generator stopped paused working script jsfunction thisIsGenerator some codeyield stops hereyield yield yield yield const genObj thisIsGenerator console log genObj next OutputNow if we were to run the next method three times observe that we would get three values up to because it would start from the beginning of our function and yield pause until it reached the next statement and then resume from where it left off to yield and then pauses once more before moving on to the next statement and finally yielding out script jsfunction thisIsGenerator some codeyield pauses some codeyield pauses some codeyield pausesyield yield const genObj thisIsGenerator console log genObj next console log genObj next console log genObj next OutputLet s see what occurs when we run it a sixth time just to be sure script jsfunction thisIsGenerator some codeyield pauses some codeyield pauses some codeyield pauses some codeyield pauses some codeyield pauses const genObj thisIsGenerator console log genObj next console log genObj next console log genObj next console log genObj next console log genObj next console log genObj next OutputIf we ran it a sixth time as you can see there would be no more code to run so our value would be set to undefined and our done would be set to true Executing Multiple GeneratorsOne more thing to remember about generators is that they can all be running at the same time and simultaneously Assume we create two generator objects both of which are based on our main generator So if we alternately executed our generator operator with our new generator object and executed it you will notice that it prints out the initial value and then it starts back at the value for our second generator object and the code continues alternately in the same pattern script jsfunction thisIsGenerator yield yield yield yield yield const genObj thisIsGenerator const genSecondObj thisIsGenerator console log genObj next console log genSecondObj next console log genObj next console log genSecondObj next console log genObj next console log genSecondObj next console log genObj next console log genSecondObj next console log genObj next console log genSecondObj next console log genObj next console log genSecondObj next Output This phenomenon occurs because whenever you call the generator object you are essentially creating a brand new instance that does not get reset that is entirely separate and has its own version of this particular function that can iterate through things on its own and allows you to do the iteration on their own Where is Generators used One of the most frequent uses for generators is when you want to perform an infinite loop In JavaScript you can t perform an infinite loop because it will loop indefinitely and cause your program to freeze However by using a generator you can perform an infinite loop that doesn t cause your PC to freeze to death because each step is only executed once If you need to say generate unique numbers and identifications this capability is incredibly helpful So let s create an infinite loop inside of our generator and try to go through each bits and pieces script jsfunction infinite let index while true yield index index const genObj infinite console log genObj next console log genObj next console log genObj next console log genObj next console log genObj next OutputAt first we first created our index variable and gave it an initial value of inside of our generator function and after that we created an infinite while loop Inside of this infinite while loop we yielded out our index and then we went on to increment it So voilà we just made a generator that when used repeatedly would produce a unique number Return MethodThe return method in generators is really quite interesting since it allows you to essentially exit out of a generator no matter how much farther on code you have to go It will also just return spit it out whatever value you feed to it Let s update our previous code and continue with the bit by bit explanation script jsfunction infinite let index while true yield index index const genObj infinite console log genObj next console log genObj next console log genObj return console log genObj next console log genObj next Let s examine the result of the above code by leaving everything else in the code unchanged and only passing return to it OutputWe will get as an value that is because we are passing to return and after that our done is set to true and undefined as being returned as our value that is because when we call return it is exiting out of our generator function as if it finished and its just going to return this value rightaway So It immidiately exits our generator and does not allow us to have any more information in our generator at all this is a really great feature if you need to exit out of the generator prematurely you can just use this return method and its going to exit out immideietly When we use return our generator function exits as if it has finished executing the entire code and it will immediately return the value that we passed to it So in the code above we will receive as a value because we passed to return The output following that return statement halted execution giving us done set to true and value as the undefined Therefore if you need to exit the generator early you can just call the return method and it will do so immediately This is a pretty excellent feature because it prevents us from having any additional information in our generator at all Throw methodSimply throwing an error is all that this function is used for This function is quite handy if you plan to write some javascript libraries but it s important to know that it exists in the wild To use it all you have to do is create a new instance of Error inside the throw function and pass the error message to it script jsfunction infinite let index while true yield index index const genObj infinite console log genObj next console log genObj next console log genObj throw new Error There is an error console log genObj next console log genObj next Output IteratorAn iterator is an object which defines a sequence and potentially a return value upon its termination Iterators also allow you to iterate over an object Specifically an iterator is any object which implements the Iterator protocol by having a next method that returns an object with two properties value It represents the current value in the sequence done It represents whether the iteration is complete or not Iterator object can be deliberately iterated after creation by periodically executing next method script jsfunction thisIsGenerator someArray for let i i lt someArray length i yield someArray i const genObj thisIsGenerator First Second Third Fourth console log genObj next console log genObj next console log genObj next console log genObj next console log genObj next OutputSo if you wish to use an array in this iterator style syntax mannerーwhich is not mandatorily requiredーthe above mentioned code is a really nice example of how to do so When building any type of JavaScript library iterators come in quite helpful If you are coming from another programming language like Java C amp C you will be highly familiar with iterators because they are used frequently in those other languages The concept behind the generators is to enable you to quickly generate iterators without having to put in the time consuming work in the background ConclusionFinally we learnt all there is to know about JavaScript generators including the fundamentals and how to get started To summarize what we learned in this article we learned about what a generator in JavaScript is and why they are so helpful in our day to day life Then we learned about the fundamentals of the generator followed by some examples of its uses cases and finally we proceeded towards the iterators and some advanced concepts about
