# What is the purpose of async and await in JavaScript? Provide an example.

`async` and `await` are used to handle **asynchronous** operations more **synchronously**. `async` marks a function as **asynchronous**, and `await` pauses the function execution until the promise resolves.

## Example:

```javascript
<script type="text/javascript">
	async function fetchData() {
	  try {
	    let response = await fetch('https://jsonplaceholder.typicode.com/users');
	    let data = await response.json();
	    console.log(data);
	  } catch (error) {
	    console.error(error);
	  }
	}
	fetchData();
</script>
```
