 JavaScript has support for single and multi line comments. Comments are ignored by the JavaScript engine, therefore have no side-effects on the outcome of the program. They should be used to document the code for future developers (including yourself!). There are libraries available that can generate project documentation pages based on commenting conventions used, [JSDoc](http://code.google.com/p/jsdoc-toolkit/, "JSDoc Toolkit") is one of the more popular ones.
