What is async/await relative to Promise?

• A. It is used for synchronous code.
• B. It replaces Promises.
• C. Async/await is syntactic sugar that makes Promise-based code read like synchronous code.
• D. It's a separate API.

Answer: (C)

Async/await is a syntax feature that lets you write asynchronous operations in a way that resembles synchronous code, while still using Promises under the hood. When you mark a function as async, you can use await inside it to pause until a Promise settles, then continue with the resolved value or throw an error if the Promise rejects. This makes sequences of asynchronous steps easier to read and reason about, and it pairs naturally with try/catch for error handling. The important point is that the asynchronous work is not removed or made synchronous; the function still returns a Promise, and awaiting it yields a value once the Promise resolves. It doesn’t replace Promises and it isn’t a separate API—it's a convenient, readable layer built on top of Promises.
