Info

constructing objects with getters that access a public property is faster than objects with getters inside a closure, but is that also the case if you run the getter method many times?

Preparation code

 
<script>
  Benchmark.prototype.setup = function() {
    function PrivateObject( item ) {
      this.getItem = function() {
        return item;
      };
    }
    function PublicObject( item ) {
      this._item = item;
    }
    PublicObject.prototype.getItem = function() {
      return this._item;
    };
    item1 = new PrivateObject( 1337 );
    item2 = new PublicObject( 1337 );
  };
</script>
