JavaScript Event Loop Explained: Async Code & Browser

Hello! If JavaScript Event Loop sounds like a made-up word to you right now, you are not alone. You’ve probably been hearing about JavaScript Event Loop everywhere and wondering what the fuss is about.

Myth 1: JavaScript is Always Asynchronous

You have probably run into this before and wondered — why does this not work? The cool part is, it’s not always asynchronous. Here’s the thing: async code is like a queue, one task at a time.

Ever wondered why some tasks seem to happen instantly? It’s because they are not async. Sound familiar? You’re getting the hang of this!

Myth 2: The JavaScript Event Loop is Only for Browsers

The JavaScript Event Loop is not just for browsers. You can use it with Node.js too. Don’t worry — it clicks eventually. The JavaScript Event Loop is like a manager, handling tasks and callbacks.

Remember, the JavaScript Event Loop is single-threaded, but it can handle multiple tasks at once, making it seem multi-threaded.

Make sense so far? You’re doing great! Transitioning to async code can be tough, but you got this.

Myth 3: Async Code is Always Hard to Understand

Async code is not always hard to understand. You just need to know how the JavaScript Event Loop works. Here’s the thing: it’s like a game of telephone, where each task is passed to the next one.
