Function.prototype.new

gistfile1.js

Function.prototype.new = function() {
    var obj = Object.create(this.prototype);
    this.apply(obj, arguments);
    return obj;
};

function Person(name) {
    this.setName(name);
}

Person.prototype.getName = function() {
    return this.name;
};

Person.prototype.setName = function(name) {
    this.name = name;
};

var david = Person.new('Dave');

david.getName(); // 'Dave'
