Hi, 
which should be the good approach to write javascript code and why?
1) 
var myClass = function(){}
myClass.prototype.init = function(x, y){
        this.width = x;
        this.height = y;
    }
myClass.prototype.show = function(){
        alert("width = "+ this.width+" height = "+ this.height);
}
2) 
var myNewClass = {
        init : function(x, y)
        {
            this.width = x;
            this.height = y;
        },
        show : function()
        {
            alert("width = "+ this.width+" height = "+ this.height);    
        }           
    }
