Benchmark: Substring from second and from fifth character, within 10 characters

Script Preparation code:

var set = [];
for (var idx = 0; idx < 1000; idx++)
{
  set.push("_" + (Math.random().toString().substring(2)));
}

Tests:

Normal access
var asd = null; for (var idx = 0; idx < set.length; idx++) { asd = set[idx]; }
Substring from second character
var asd = null; for (var idx = 0; idx < set.length; idx++) { asd = set[idx].substring(1); }
Substring from fifth character
var asd = null; for (var idx = 0; idx < set.length; idx++) { asd = set[idx].substring(1); }
