Both constructs (catch () being a syntax error, as sh4nx0r rightfully pointed out) behave the same in C#. The fact that both are allowed is probably something the language inherited from C++ syntax. , can throw objects that do not derive from System.Exception. In these languages, catch will handle those non-CLS exceptions, but catch (Exception) won't.
Does using the 'catch, when' feature make exception handling faster because the handler is skipped as such and the stack unwinding can happen much earlier as when compared to handling the specific use cases within the handler?

In the second scheme, if the promise p rejects, then the .catch() handler is called. If you return a normal value or a promise that eventually resolves from the .catch() handler (thus "handling" the error), then the promise chain switches to the resolved state and the .then() handler after the .catch() will be called. So that's difference #2.
I'm a student in my first C++ programming class, and I'm working on a project where we have to create multiple custom exception classes, and then in one of our event handlers, use a try/catch block...
Try-catch is meant to help in the exception handling. This means somehow that it will help our system to be more robust: try to recover from an unexpected event. We suspect something might happen...
You cannot use Try/Catch with ErrorAction SilentlyContinue. If you want to silently handle the errors, use Stop for your ErrorAction, and then use the Continue keyword in your Catch block, which will make it continue the loop with the next input object:
