Promise

An object representing the eventual completion or failure of an asynchronous operation. A Promise is in one of three states: pending, fulfilled, or rejected. Promises can be chained with .then() and .catch().

Async/Await

Syntactic sugar built on top of Promises that makes asynchronous code look and behave like synchronous code. async functions always return a Promise, and await pauses execution until a Promise resolves.
