In this tutorial, you have learned about the JavaScript event loop, a constantly running process that coordinates the tasks between the call stack and callback queue to achieve concurrency.

Apr 15, 2025 · The event loop is an important concept in JavaScript that enables asynchronous programming by handling tasks efficiently. Since JavaScript is single-threaded, it uses the event loop to manage the execution of multiple tasks without blocking the main thread.

Dec 16, 2024 · The event loop is a core concept in JavaScript that enables non-blocking, asynchronous behavior. Understanding how the event loop works is essential to mastering JavaScript, especially...

But first, what is the event loop and why should you care? JavaScript is single-threaded: only one task can run at a time.

Apr 4, 2024 · Learn how the browser event loop, task queue, microtask queue, and Web APIs work together to enable non-blocking, asynchronous JavaScript.

The JavaScript event loop manages asynchronous tasks in a single-threaded environment. I explore how it works with the call stack, task queue, and microtasks.
