Async and await are modern JavaScript features that make asynchronous code look and behave like synchronous code.
Instead of using long chains of then() and catch(), async and await allow developers to write clean, readable, and easy-to-understand code.
They are widely used when working with APIs, server requests, and any task that takes time to complete.
Why Use Async and Await
- Makes asynchronous code easier to read
- Reduces nested callbacks
- Looks like normal step-by-step code
- Simplifies error handling
- Used in modern frameworks and projects
Async and await make complex logic simple.
When a function is marked as async, it always returns a promise.
The returned value becomes the resolved value of that promise.
The await keyword pauses the function until the promise is resolved.
This makes asynchronous code behave like synchronous code.
These examples show how async and await make asynchronous programming easier and cleaner.
By mastering async and await, students gain the ability to write modern, readable, and professional JavaScript code for real-world applications.
