Asynchronous JavaScript & Event Loop
Understand asynchronous programming patterns, callbacks, Promises, async/await, and the Node.js event loop.
What is Asynchronous Code?
Asynchronous code lets Node start a slow task — a file read or network call — and keep running other code instead of blocking the main thread.
