await — Handling rejected promises

If the Promise is rejected, the rejected value is thrown. You can handle rejected promises without a try block by chaining a catch() handler before awaiting the promise. This is built on the assumption that promisedFunction() never synchronously throws an error, but always returns a rejected promise

You can handle rejected promises without a try block by chaining a catch() handler before awaiting the promise. This is built on the assumption that promisedFunction() never synchronously throws an error, but always returns a rejected promise. This is the case for most properly-designed promise-based functions, which usually look like However, if promisedFunction() does throw an error synchronously, the error won't be caught by the catch() handler. In this case, the try...catch statement is necessary. Attribution: Adapted from MDN Web Docs under CC-BY-SA-2.5.
