Understanding Async/Await in JavaScript

Async/await makes asynchronous code easier to read and write in JavaScript.

What is Async/Await?

Async/await is syntactic sugar built on top of Promises, making asynchronous code look synchronous.

Basic Example

async function fetchData() {
  try {
    const response = await fetch('/api/data');
    const data = await response.json();
    return data;
  } catch (error) {
    console.error('Error:', error);
  }
}

Benefits

  • Cleaner code than callbacks
  • Better error handling
  • Easier to read and maintain
  • Works with try/catch

Async/await simplifies working with asynchronous operations in JavaScript.
