Error Handling in Async Functions
script.js
When working with async functions in JavaScript, you may encounter errors that occur while awaiting Promises. If a Promise is rejected inside an async function, the error will be thrown at the point of the await expression. This means that, just like in synchronous code, you can use a try/catch block to catch and handle errors. This approach makes asynchronous error handling feel much more like traditional synchronous error handling, where you wrap potentially error-prone code in a try block and respond to failures in the catch block. If you do not use a try/catch block, any unhandled errors in the async function will cause the returned Promise to reject, and you would have to handle those errors with a .catch method when calling the async function. Using try/catch inside the async function itself allows you to manage errors locally and even perform cleanup or logging before rethrowing or handling the error.
