How Can One Javascript Enclosure Internal Function Call Another Internal Function

Question

How can func2 call func1 within the same Javascript enclosure? Is this even possible?

var x = (function() {

    return {
        func1: function func1() {},
        func2: function func2() {
            var y = func1();  // Doesn't work! What does?
        }
    }

}());

Answer 1

Define func1 before you return, then assign a reference to func1 as a property of your return object.

var x = (function() {
    function func1() {}

    return {
        func1: func1,
        func2: function func2() {
            var y = func1();
        }
    }

}());

Answer 2

var x = (function() {

return {
    func1: function func1() {},
    func2: function func2() {
        var y = this.func1();
    }
}

}());
