What happens if an error occurs inside an `async/await` function? How does it relate to `.catch()`?

Errors inside `async/await` functions are effectively treated like synchronous exceptions. You can use a standard `try...catch` block to handle them. The `try...catch` block serves a similar purpose to a `.catch()` block in Promise chains, allowing you to intercept and handle errors that occur during asynchronous operations. `await` simplifies error handling by making asynchronous code look synchronous.
