应该如何在小，中，大型应用开发中组织前端js代码？

function a(){};
function b(){};

var obj = {
init : function(){
this.a();
this.b();
},
a : function(){},
b : function(){}
}
// 在页面中调用obj.init();

var hogo = {
ns : function(){};
}

hogo.ns('hogo.wx', {
init : function(){
this.a();
this.b();
},
a : function(){},
b : function(){}
});
hogo.wx.init();
