Script Preparation code:

var array = new Array(100);

Tests:

for (dynamic length)
var i = 0; for (; i < array.length; ++i) { array[i]; }
foreach
array.forEach(function(i) { array[i]; });
some
array.some(function(i) { array[i]; });
for..of
for (var i of array) { array[i]; }
for (static length)
var len = array.length var i = 0; for (; i < len; ++i) { array[i]; }
backward for
var i = array.length - 1 for (; i >= 0; --i) { array[i]; }
