Question

So I admit that I’m new to javascript and that I come from a C.+ background (‘Hi, I’m Bob, I’m a class-based static language user’, chorus ‘hi Bob!’).

I find that I often end up writing functions like:

function someFunc() {     if (arguments.length === 0 ){        ...     } else {        ...     } } 

(where there might be three such cases). Or, alternatively, I write the difference into the name:

function someFuncDefault() { ... }; function someFuncRealArg(theArg) { ... }; 

(Substitute ‘RealArg’ for some semantically contentful phrase).

Is there a better pattern for this kind of thing?
