Benchmark: Array split vs Array split limit vs string substring

Script Preparation code:

var s1 = "foo.bar";
var s2 = "foo.bar.bla.boo.foo.bar";

Tests:

Array.split limit
var n1 = s1.split(".", 1)[0]; var n2 = s2.split(".", 1)[0];
Substring
var n1 = s1.substring(0, s1.indexOf(".")); var n2 = s2.substring(0, s2.indexOf("."));
Array.split
var n1 = s1.split(".")[0]; var n2 = s2.split(".")[0];
