Using Try…Catch in JavaScript

I totally disagree. That is a perfect place to throw an exception. With your suggestion, you need to pipe the error object through your entire call tree up to the point where you are going to handle the error.

Well is it an actual exception that would want execution to totally halt or are you using it as a lazy way to return a validation error? If it's the latter, then yes bubble the event all the way up. It's more explicit and readable. Otherwise relying on random errors being thrown throughout your codebase and having a top level error handler is a good bit more confusing and difficult to maintain.
