JavaScript loops are fundamental control structures that allow developers to execute a block of code repeatedly. There are primarily three types of loops in JavaScript: for, while, and do...while. Below, a detailed explanation of each type with examples: For Loop The for loop iterates over a...
You can do the same with a for..in loop to iterate on an object:const fun = (prop) => { return new Promise(resolve => { setTimeout(() => resolve(`done ${prop}`), 1000); }) } const go = async () => { const obj = { a: 1, b: 2, c: 3 }; for (const prop in...
How to run async loops in sequence or in parallel? Before doing asynchronous magic with loops I want to remind you how we write classical synchronous loops. 😐 Synchronous loop Long time ago I was writing loops like this (probably you too): for (var i=0; i < array.length; i++) {...
Learn about for...in loops in JavaScript: their syntax, how they work, when to use them, when not to use them, and what you can use instead.
In this article, we will explore how to utilize loops in JavaScript to iterate through array elements. JavaScript offers several types of loops:for loop executes a code block for a specified number of iterations. forEach() executes a function for each element in an array or NodeList. for.....
JavaScript doesn’t have a dedicated sleep() function that causes the code to wait before resuming execution. Here's how to write a JavaScript sleep function.
In JavaScript, the array data type consists of a list of elements. There are many useful built-in methods available for JavaScript developers to work with ar…
//run game code here } }); timer.start(); timer.stop(); So there you have it perfectly synched time in all browsers. This is probably about as accurate as you can get and it adds a very tiny foot print to your game loops.

Long answer: I had the need to shuffle the elements in a JavaScript array. In other words, I wanted to remix the array elements, to have them in a different order than the previous one. [1,2 I wanted something different any time I ran the operation, like this: ...
