How Async/Await, Promises & the Event Loop Really Work in JavaScript (Visual + Real Example)
Detailed technical article link : https://jwaran78.medium.com/d4d3db76e0a9
In this video, I’ll show you how async/await, Promises, and the Event Loop work behind the scenes in JavaScript — using a real Next.js example.
We’ll look at single, sequential, and parallel API calls, and visualize how JavaScript handles them using the call stack, Web APIs, and queues.
Super simple explanation with code, console logs, and diagrams.
