Answer
A promise represents a future value and helps avoid callback nesting with cleaner chaining.
Quick Answer
A Promise is an object representing the eventual completion (or failure) of an async operation. Instead of nested callbacks (callback hell), you chain .then() and .catch(). A Promise is in one of three states: pending, fulfilled (resolved with a value), or rejected (rejected with an error). Cleaner than callbacks for async code.
