What is meant by 'JavaScript Namespacing'? [duplicate]

Answer 1

I use this namespacing technique, along with "use strict" outlined by Crockford

var MyNamespace = (function () {
    "use strict"; 

    function SomeOtherFunction() {

    }

    function Page_Load() {

    }

    return { //Expose 
        Page_Load: Page_Load,
        SomeOtherFunction: SomeOtherFunction
    };
} ());

MyNamespace.Page_Load();
