What are async and await in JS?

async: Declares a function as asynchronous. It always returns a Promise.

await: Pauses the execution of an async function until the Promise is resolved or rejected.

Why do we use async and await?

• To make asynchronous code look and behave more like synchronous code.
• It improves readability and avoids callback hell or complex .then() chains.

Can you use await outside of an async function?

• No, await can only be used inside an async function. Using it outside will result in a syntax error
