Async/Await in JavaScript

Async/await is syntactic sugar over Promises that makes asynchronous code look and behave like synchronous code. It's much easier to read and write than long .then chains.

Any function can be made async, and inside it you can await Promises.

Async/await is cleaner for sequential operations, while Promise.all is great for parallel.
