Getters & Setters in a prototype pattern

I'd like to use getters & setters within a prototype pattern. I did this by putting Object.defineProperty in the constructor.

I know that i can just create getWhatever() methods in the prototype object, by I like the brevity of accessing properties through real getters/setters

But having the defineProperty outside the prototype object like this doesn't feel right to me. Is there a better way?

function Person(name) {
    this._name = name;

    Object.defineProperty(this, 'name', {
        get: function() {
            return this._name;
        }
    });
}

Solution

  • Why not do it on the prototype itself?

    function Person(name){
    this._name = name;
}

Object.defineProperty( Person.prototype, 'name', {
    get:function(){ return this._name; }
})
