give me an example of error handling?any one

When you make a mistake in a typescript the editor marks it, usually with a red pen or pencil. That's error handling of a kind.

Seriously, though, this is way too vague a question. Is it an interview question? As with any other programming tool, error handling is about anticipating errors of various kinds and implementing mechanisms that can intercept and, hopefully, ameliorate them. Prevention is an even better approach.
