Mastering JavaScript Async/Await

Async/await makes asynchronous code look and behave more like synchronous code. Let's master it!

Understanding Promises First

Before diving into async/await, you need to understand Promises.

The Async Keyword

The async keyword makes a function return a Promise.

The Await Keyword

The await keyword makes JavaScript wait until a Promise settles.

Error Handling

Use try/catch blocks to handle errors in async functions.

Best Practices

1. Always handle errors
2. Don't forget to await
3. Use Promise.all for parallel operations
4. Avoid mixing callbacks with async/await

Conclusion

Async/await is a game-changer for writing asynchronous JavaScript code.
