Variables not showing in Firebug

I'm still getting to grips with some of the JavaScript variable handling and I'm a bit confused over this.

I have a variable declared in a file like this:

(function (myControls, $, undefined) {

    var selectedLifeArea;
    ...

But when looking for these in Firebug they aren't listed under the myControls "namespace" as I expected, only the functions are listed. Why is that?

Your code is wrapped in it's own scope.

Try adding some breaks in the js debugger, then you can read the variables.

Here is a brief description:

var globalVariable;

(function () {

    var localVariable;

    // can access both `globalVariable` and `localVariable`
    ...
)();

// can only access `globalVariable`
