How do I handle exceptions in asynchronous code?

In asynchronous code, you can handle exceptions using try-catch blocks within async functions or by using .catch() with Promises.

Can you give me an example of using try-catch in async functions?

Sure! 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 about handling errors with Promises?

You can handle errors in Promises using the .catch() method. For example:

fetch('https://api.example.com/data')
    .then(response => response.json())
    .catch(error => console.error('Error:', error));

Are there any best practices for exception handling in async code?

Yes, some best practices include always handling errors, using centralized error handling, and logging errors for debugging.
