Question

So i’m setting up an object with private and public methods. Basically using the following format:

var Utility = function() {
    var prive1, priv2, priv3;
    function privateMethod1() { //do something }

    return {
        publicFunc1: function() { //do something different }
        publicFunc2: function() { //do something else }
    }
}

But i’m worried about some of the situations i’m coming across where publicFunc2 needs to call publicFunc1. For Example the way I would do this atm is:

publicFunc2: function() { Utility.publicFunc1(); //then do something else }

is this OK? It runs, but it seems weird and VS2010 doesn’t give me . I believe that if someone was to change the line
var Utility = function() { –> to –> var Utility2 = function() {}
then essentially everything would be broken from within the object and that seems wrong…
but i’m at a loss on what i should actually be changing.
Should i be making all methods basically private and then mapping to a public function? EX:

{
    function privateFunc1() {}

    return {
        publicFunc1 : privatefunc1
    }
}

or should i have a completely different approach to accomplish the idea of private and public methods and variables?

If you want to call some function – give it a name and call it by that name:

var Utility = function() {
    var prive1, priv2, priv3;
    function privateMethod1() { //do something }

    function Func1() { //do something different }
    function Func2() { Func1(); //do something else }

    return {
        publicFunc1: Func1,
        publicFunc2: Func2
    };
}

Call of local function by name is always faster than any other method of call in JS.
