Array vs Object Access (v6)

Revision 6 of this benchmark created by David 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= {1:1, 2:2, 3:3, 4:4, 5:5, 6:6, 7:7, 8:8, 9:9, 10:10};
