Understanding Async/Await in JavaScript

Async/Await makes asynchronous code readable and manageable.

1. Async Functions

An async function always returns a Promise.

async function fetchData() {
  return "Hello";
}

2. Await Keyword

Use await to pause execution until the Promise resolves.

const result = await fetchData();

3. Error Handling

Wrap await calls in try/catch for safe handling.

Best Practices

• Avoid mixing callbacks with async/await.
• Handle errors properly.
• Use Promise.all for concurrent tasks.
