Prototype for private sub-methods

Question

I have code that looks like this:

var baseClass = function() {
// CODE
    var subClass = function() {
        // MORE CODE
    }
}

Adding meth

If you really want to keep the subclass private, you could hide the definitions in a closure:

var BaseClass = (function() {
    function BaseClass() { ... };
    function SubClass() { ... };
    BaseClass.prototype.foo = function() { ... };
    SubClass.prototype.foo = function() { ... };
    return BaseClass;
})();

I have personally found this kind of closure-enforced protection to be more trouble than it's worth (ex, makes debugging more difficult)… But if you wanted to do it, that's how you would.
