Why this behaviour?__proto__ vs prototype?

Question

    function Obj1(name){
        this.__proto__={
            Name:name,
            getName:function(){
                alert(this.Name); 
            }


        }         


        

Answer 1

Only functions has the property prototype. You need to set the prototype on the function self.

function Obj2(name){
    this.name = name;
}

Obj2.prototype={
    getName:function(){
       alert(this.Name); 
    }
};
