Simplify JavaScript’s Async Concepts with One GIF

Have you ever wondered how JavaScript manages to handle asynchronous tasks while ensuring smooth and responsive web applications? The answer lies in the JavaScript Event Loop, a fundamental concept that governs the execution of code. In this blog post, we’ll break down the key components of the event loop and how they work together to keep your web applications running seamlessly.

Here’s how the event loop works:

Call Stack

The Call Stack is where all your JavaScript code is executed. When you call a function, it’s added to the stack, and JavaScript executes functions in a “last in, first out” (LIFO) order. In other words, the last function added to the stack is the first one to be executed. This stack structure ensures that JavaScript functions run from top to bottom.

Web APIs

For time-consuming tasks like fetching data from a server, performing animations, or handling other resource-intensive operations, JavaScript leverages Web APIs provided by the browser…
