light-weight argument validator
Ridiculously light-weight argument validator with Node.js that is an event-based server-side JavaScript engine
This JavaScript engine can help you to do argument validation in easy manner. It is easier and concise to use than that of assertions. The types are specified by a single character and there is nothing like optional argument.
