What is Asynchronous JavaScript?

JavaScript runs on a single thread, but many operations (network requests, timers, file I/O in Node, etc.) are asynchronous. This means they can start now and finish later without blocking the main thread.

Modern JavaScript offers async/await syntax built on top of Promises for a clean, linear style.
