JavaScript Visualized: Event Loop, Web APIs, (Micro)task Queue

Learn how JavaScript's Event Loop manages asynchronous operations in a single-threaded environment. This visual guide explains the Call Stack, Web APIs, Task Queue, and Microtask Queue - covering how callbacks and promises are handled differently, why microtasks have priority, and how the Event Loop orchestrates non-blocking JavaScript execution. Essential knowledge for understanding async/await, setTimeout, fetch, and other asynchronous JavaScript patterns.
