prototype vs closures (v56)

Revision 56 of this benchmark created by Peter Lisovin on

Setup

'use strict';
  
  function get_name() {
    return this.name;
  }
  
  function set_name(name) {
    this.name = name;
  }
  
  function do_something_useful(n) {
    var i,
        sum = 0;
    for (i = 0; i < n; i += 1) {
      sum += i;
    }
    return sum;
  }
  
  function Person(name) {
    this.name = name;
  }
  Person.prototype.get_name = get_name;
  Person.prototype.set_name = set_name;
  Person.prototype.do_something_useful = do_something_useful;
  
  var person = function(name) {
    return {
      name: name,
      get_name: get_name,
      set_name: set_name,
      do_something_useful: do_something_useful
    };
  };
  
  var p = new Person('John');
  var c = person('John');
