What are event loops?

An event loop is like having a friendly helper who never stops working to make sure everything gets done on time.

Imagine you're playing with your toys in your room. You have a friend who helps you by doing different tasks, sometimes they bring you a snack, sometimes they clean up your blocks, and sometimes they read you a story. But instead of stopping when one task is done, they keep going, always ready to help with the next thing that comes up.

That's what an event loop does in computers, it helps programs handle many things at once without getting confused or slowing down.

How It Works

Think of your friend as the event loop, and each task you ask them to do is like an event. They don’t stop doing one thing just because another comes up, they keep switching between tasks, making sure everything gets done smoothly and quickly.

So whether it's a snack, a story, or a game, your friend (or the event loop) makes sure you never have to wait too long for what you want next.
