There is no official concept of a namespace in Javascript like there is in C++. However, you can wrap functions in Javascript objects to emulate namespaces. For example, if you wanted to write a function in a "namespace" called MyNamespace, you might do the following:

var MyNamespace = {};

MyNamespace.myFunction = function(arg1, arg2) {
    // do things here
};

MyNamespace.myOtherFunction = function() {
    // do other things here
};

Then, to call those functions, you would write MyNamespace.myFunction(somearg, someotherarg); and MyNamespace.myOtherFunction();.

I should also mention that there are many different ways to do namespacing and class-like things in Javascript. My method is just one of those many.
