Revision 25 of this benchmark created on

Description

Added native js forEach to the comparisons plus from version 6 added passing the value from array to each test in order to make the test more meaningful all around.

Added simple ForEach function for demonstration.

Added Lazy.js, Zepto and minimal.js in version 8
