Benchmark: Array isArray vs instanceof vs isEqual vs isLessThan22

Script Preparation code:

var test = [[1],2,3,4];
var test2 = [-1, 2, 3, 4];
var test3 = ['a', 2, 3, 4];
var c;

Tests:

Instanceof
if (test[0] instanceof Array) { c++; }
isArray
if (Array.isArray(test[0])) { c++; }
isEqual
if (test3[0] === 'a') { c++; c+=2; c+=5; var z = c + 5; var x = z + c + 5; x++; }
isLessThan
if(test2[0] < -1) { c++; c+=2; c+=5; var z = c + 5; var x = z + c + 5; x++; }
