JS defineProperty and prototype

Question

As you know we can define getters and setters in JS using defineProperty(). I\'ve been stuck when trying to extend my class using defineProperty().

Answer 1

Please don't implement any other version because it will eat all your memory in your app:

var Player = function(){this.__gold = 0};

Player.prototype = {

    get gold(){
        return this.__gold * 2;
    },



    set gold(gold){
        this.__gold = gold;
    },
};

var p = new Player();
p.gold = 2;
alert(p.gold); // 4

If 10000 objects are instantiated:

• With my method: you will only have 2 functions in the memory;
• With the other methods: 10000 * 2 = 20000 functions in the memory;
