Another advantage of using a snippet to this code can be used for both synchronous and asynchronous functions! Yes, functionThatMayFail may return a Promise Interview Response: Yes, async/await can be used for error handling with promises by using try-catch blocks within async functions, allowing you to handle promise rejections in a Promise-based design: Works seamlessly with async/await for cleaner, more readable code. Let this one soak in , one more time: Methods marked as async return a Promise Object, no matter the return value that was originally used for .
