How do I use try-catch in async functions in Node.js?

How do I use try-catch in async functions in Node.js?

You can use try-catch blocks to handle errors in async functions. Here's a simple example:

async function fetchData() {
    try {
        const response = await fetch('https://api.example.com/data');
        const data = await response.json();
        return 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 a rejected promise, which can crash your application if not handled.

Can I use try-catch with multiple await statements?

Yes, you can! Just wrap the entire block of code with await statements in a single try-catch to handle any errors that may occur.

Are there any best practices for using try-catch?

It's best to keep the try block small, only wrapping the code that might throw an error. This makes debugging easier and improves performance.
