Array vs Object Access (v7)

Revision 7 of this benchmark created on

Description

JavaScript arrays are basically just objects with integer property names. Is there any performance difference when accessing an array vs an object?

a= [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
    o= {"a":1, "b":2, "c":3, "d":4, "5":5, "6":6, "7":7, "8":8, "9":9, "10":10};
