Loupe is a little visualisation to help you understand how JavaScript's call stack/event loop/callback queue interact with each other. The best thing to do to understand how this works is watch this video, then when you are ready, go play!

Nov 20, 2019 · I’m a visual learner so I thought I’d try to help you by explaining it in a visual way through low-res gifs because it's 2019 and gifs are somehow still pixelated and blurry. But first, what is the event loop and why should you care? JavaScript is single-threaded: only one task can …

The event loop is a constantly running process that monitors both the callback queue and the call stack. If the call stack is not empty, the event loop waits until it is empty and places the next function from the callback queue to the call stack.

Oct 7, 2023 · We’ll explore how the event loop coordinates tasks, how the call stack and callback queue come into play, and how modern JavaScript features like Promises and async/await simplify the...

Dec 31, 2013 · The solution is to use an “Event Loop” when you want to animate to this degree. The basic idea is to have your code loop over and over. Each loop will execute your code and at the end of the loop will repaint to display the updated view. The simplest and beginner approach to do this would be to use the setInterval command.

Jan 20, 2015 · You can use setInterval() and then clearInterval() to stop, or read up on recursion schillmania.com/content/projects/javascript-animation-1 . If you want to try the more modern way, try googling for "requestAnimationFrame"

In JavaScript, an event loop is a mechanism that allows the execution of code to be scheduled in a non-blocking way. That means the code can continue to run and handle new events as they occur without being stopped or blocked by long-running operations.

Oct 29, 2023 · At the core of JavaScript’s asynchronous nature lies the event loop, a fundamental concept for managing non-blocking operations. The event loop is responsible for handling tasks, categorising them into two main types: macro tasks and micro tasks.

Nov 5, 2022 · * The event loop connects the queue with the call stack. It checks if the latter is empty and moves the first queue item for execution. The code is available at https://github.com/fabrilallo/event-loop-1. Try to figure out what the …
