prototype vs closures (v40)

Revision 40 of this benchmark created by David on

Setup

var Person = function (name, lastname, age) {
  	this.name = name;
    this.lastname = lastname;
    this.age = age;
  }
  
  Person.prototype.get_name = function() {
  	return this.name;
  };
  
  Person.prototype.toString = function() {
  	return this.name+' '+this.lastname+' ('+this.age+')';
  };
  
  
  
  var person = function(name, lastname, age) {
  	return {
  		'get_name': function() {
  			return name;
  		},
      'toString': function() {
        return name+' '+lastname+' ('+age+')';
      }
  	};
  };
  
  _p = [];
  _c = [];
  var i;
  for (i = 0; i < 100; ++i) {
    _p.push(new Person('John', 'Doe', 42));
    _c.push(person('John'));
  }
