海外TECH	DEV Community	Smooth CSS Gradient Transitions	https://dev.to/smpnjn/smooth-css-gradient-transitions-3d2j	Smooth CSS Gradient TransitionsIf you try to animate or transition a gradient in pure CSS we end up with a an issue all modern browsers do not natively transition colours in gradients smoothly As such if we try to hover or interact with an element which transitions from one gradient to another we end up with a sudden change even when used with something like transition all s ease out Animating and Transitioning Gradients with CSS and JavascriptIn this article we ll be looking at how to solve this problem and we ll cover how to smoothly animate a gradient transition with Javascript That means creating a function which will be able to transition between two colors smoothly The full code for all of this can be found on codepen here Although there is no native way to do this effect we can do it with Javascript The below button solves the problem allowing us to smoothly animate gradient transitions with Javascript and some CSS when you hover over the button Transitioning between two gradients in CSS smoothly The first step is we need to create a function which allows us figure out a color between two colors For this to work we ll need the color we start with and the one we want to transition to The function we ll create is shown below It can support gradients with more than colors but for this we ll just use two We ll also take the initial gradient color and apply that to our button so we can manipulate the gradient completely from our Javascript let element gradient button transition lt id of the button we re transitioning DEFINE YOUR GRADIENT COLORS HERE Pct refers to the percentage position of the gradient stop point const gradientStopOne pct color r g b The first color in your gradient pct color r g b The color you want your first color to transition to const gradientStopTwo pct color r g b The second color in your gradient pct color r g b The color you want your second color to transition to Apply our gradient programmatically so we can completely manipulate the gradient from JS rather than CSSlet c gradientStopOne color let c gradientStopTwo color document getElementById gradient button transition style background linear gradient angle deg rgb c r c g c b rgb c r c g c b This function transitions between two rgb colorsconst getColor function pct colorSet for var i i lt colorSet length i if pct lt colorSet i pct break This conversion figures out the transition between two rgb values var lower colorSet i var upper colorSet i var range upper pct lower pct var rangePct pct lower pct range var pctLower rangePct var pctUpper rangePct var color r Math floor lower color r pctLower upper color r pctUpper g Math floor lower color g pctLower upper color g pctUpper b Math floor lower color b pctLower upper color b pctUpper And returns the rgb code return rgb color r color g color b Now that we have a function which will let us transition between two colors and have defined our gradients We can start transitioning between them We ll create one function which will set an interval depending on whether the user hovers or not we will manipulate the direction of the animation Comments in the code below explains what we re trying to do here The interval runs every miliseconds or times a second This will give us a smooth frames per second animation Within the interval function we calculate the total number of frames and stop the animation when the transition time is up let transitionTime lt ms time our animation will lastlet previousTime start lt stores data on animationlet angle lt angle of gradientlet animationDirection forwards lt stores the animation directionlet intervalFrame lt stores the interval framelet currentPct lt current percentage through the animationlet elapsed lt number of frames which have ellapsed This is our animation which we run on hoverconst animateGradient function if intervalFrame undefined intervalFrame setInterval gt let time transitionTime time in seconds let numberOfFrames time frames per second gt second frames If the animation is going forward if animationDirection forwards Add to elapsed elapsed The elapsed frames out of max frames currentPct Math min elapsed numberOfFrames else Otherwise we re going back subtract from ellapsed elapsed The elapsed frames out of max frames currentPct Math max elapsed numberOfFrames Calculate current color in this time for each gradient color let colorOne getColor currentPct gradientStopOne let colorTwo getColor currentPct gradientStopTwo Generate CSS string let generateGradient linear gradient angle deg colorOne colorTwo Add it to our background document getElementById element style backgroundImage generateGradient End the interval when we re done if currentPct currentPct clearInterval intervalFrame intervalFrame undefined frames per second Finally we run all of this on hover in and hover out When the user hovers we update the animation direction so we can move the gradient towards the colors we want it to On hover run our animationdocument getElementById gradient button transition addEventListener mouseover function animationDirection forwards animateGradient On hover out run our animation again but backwardsdocument getElementById gradient button transition addEventListener mouseleave function animationDirection backwards animateGradient Multiple color gradient transitionsSince we can have this run for multiple colors and also run whenever we want we can create some fun effects Here is a button that automatically transitions between different gradients ConclusionAlthough not possible with CSS today Javascript actually gives us a lot more flexibility to animate our gradient transitions smoothly If you ve found this useful don t forget to subscribe or follow me on twitter You can find the full code on codepen here	2022-02-12 19:39:46
海外TECH	DEV Community	What the heck is single threaded and synchronous (JavaScript)	https://dev.to/therajatg/javascript-single-threaded-and-synchronous-what-the-heck-it-is-35a9	What the heck is single threaded and synchronous JavaScript A few days ago single threaded and synchronous were just heavy words for me If this is you right now don t worry I ll try my best to make you understand So let s get started Single threaded and synchronous are not that much different Single threaded It can do only thing at a time and has a single call stack don t worry just read and soon you ll get what it is Synchronous As the name suggests synchronous means to be in a sequence So basically a function has to wait for the earlier function to get executed and everything stops until the wait is over call stack is basically a data structure which records where in the program we are If we step into a function we push it to the top of the stack and when we return a value from the function we basically pop the function off from the stack Let s understand it by running the below code function multiply a b return a b function square n return multiply n function printSquare n let squared square n console log squared printSquare See how the above code executes There will be a main function when the file starts executing then we call printSquare which gets pushed over top of the stack which in turn calls square function which gets pushed over at the top of the stack which in turn calls the multiply function which gets pushed over at the top of the stack Now as soon as a function returns some value it gets popped off from top of the stack Even if a function does not have anything to return it gets popped off from top of the stack after its execution printSquare See below Due to this synchronous nature of JavaScript problem arises when we have a very heavy function in between which is taking seconds or more time to execute In this case everything else is stopped does not matter where you click in the browser window for some time and the call stack gets blocked until that function returns To tackle this problem in JavaScript we made JavaScript asynchronous where tasks seems to run in parallel with the help of web API s Actually it only appears to be asynchronous it still has only one call stack I ll explain this concept in my next blog and will give its link here once ready If you have any doubts feel free to post in the comment section I ll try to answer as many doubts as I can 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 Have an awesome day ahead my twitter handle therajatgIf you are the linkedin type let s connect	2022-02-12 19:10:08
