Answer

To handle errors from a rejected promise in an async function, use a try-catch block. This allows you to catch and handle any errors that occur during the execution of the awaited promises.

<!-- BEGIN COPY / PASTE -->
        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);
            }
        }

        fetchData();
        <!-- END COPY / PASTE -->

Additional Comment:

Use "try" to wrap the code that might throw an error.
Use "catch" to handle any errors that occur in the "try" block.
The "catch" block receives the error object, which you can log or handle as needed.
This pattern ensures that your code remains clean and errors are managed gracefully.
