How do I use try-catch in async code?

You can use try-catch blocks in async functions to handle errors. Just wrap your await calls in a try block.

Can you show me an example?

Sure! Here's a simple example:

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

What happens if I don't use try-catch?

If you don't use try-catch, any error thrown in the async function will result in an unhandled promise rejection, which can crash your application.

Are there any best practices for using try-catch?

Yes, it's best to keep the try block small, only wrapping the code that might throw an error, and handle specific errors when possible.
