Async/Await JavaScript

Async/await is a syntax built on top of Promises that makes asynchronous JavaScript code easier to read and write, especially in Node.js applications.

How Async/Await Works

Marking a function as async allows the use of await inside it, pausing execution until a Promise resolves without blocking the rest of the application.

Error Handling

Try/catch blocks are commonly used with async/await to handle errors from asynchronous operations in a clear, synchronous-looking way.

Common Use Cases

Async/await is widely used for database queries, API calls, and file operations, where operations naturally take time to complete.
