Async/await is a way to write asynchronous code that looks more like synchronous code, making it more readable and easier to understand. It allows for easier error handling and an overall cleaner code structure. Promises, on the other hand, are objects that represent the eventual completion or failure of an asynchronous operation, allowing for better management of asynchronous operations in JavaScript.

In terms of functionality, async/await is built on top of Promises. Async functions return a Promise, allowing for the same error handling and control flow as Promises. However, async/await simplifies the syntax for handling Promises, making it easier to write and understand asynchronous code.
