Just like PHP, JavaScript supports Exceptions - only they're called Errors. However, due to the asynchronous nature of Node.js, the classic try/catch strategy doesn't work. To catch asynchronous errors, Node strongly encourages a particular signature for callback functions. I'll explain all that shortly, but now I have a confession to make.
