JavaScript multiple namespaces

I have a large js file that I want to break into multiple namespaces.

  1. Is this a good/bad approach vs keeping everything in one namespace?

  2. In NAMESPACE_FIRST how do I call map build? 

    var NAMESPACE_FIRST = {
    init:function() {
        alert("onload functions");
    },
    this.map:function() {
        this.length = 0;
    },
    this.map.prototype.build:function(){
        return this.length;
    }
};

var NAMESPACE_SECOND = {
    upload:function() {
          //do something
    },
    delete:function() {
          //do something
    }
};

$(function () {
    NAMESPACE_FIRST.init();
});

Nice question!

Firstly, your JavaScript is a little erroneous. To achieve the effect I think you want, your first namespace should look like:

var NAMESPACE_FIRST = {

    init: function() {
        alert("onload functions");
    },
    map: function() {
        this.length = 0;

        NAMESPACE_FIRST.map.prototype.build = function() {
            alert("1");
            return this.length;
        }
    }
}

So, answering question 2, your onready will be something like: 

$(function () {
    NAMESPACE_FIRST.init();

    var obj = new NAMESPACE_FIRST.map();
    obj.build();
}

Regarding question 1, I've no real opinion either way.
