What's the difference between `try...catch` and `throw new Error()`?

The `try...catch` block is used for handling exceptions (errors) that might occur during the execution of a block of code. It allows you to gracefully manage errors without crashing the program. `throw new Error()` is used to explicitly signal that an error has occurred. You then catch that error using a `catch` block. The `try...catch` mechanism is about error handling; `throw new Error()` is about creating and raising an error.
