Understanding Asynchronous JavaScript: The Event Loop Explained
The event loop is at the heart of JavaScript's asynchronous behavior. In this post, we’ll break down how the call stack, task queue, and microtask queue interact to execute code in a non-blocking manner.
First, let’s define the call stack: it's a LIFO structure that holds the currently executing functions. When a function calls another, the new function is pushed onto the stack...
Understanding these concepts will help you write more efficient, bug‑free asynchronous code.
Great explanation! I finally understand why setTimeout with 0ms still runs after the current call stack clears.
Can you also cover how async/await fits into the event loop?
Absolutely, I’ll add a follow‑up post soon.
