Setup

var my_arr = ['z', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f'];
    var my_arr_length = my_arr.length;
    var i = 0, val;

Test runner

jQuery.each(my_arr, function(i, val) {

});

for ( var i = 0, val; (val = my_arr[i]); i++ ) {

}

for (var i = 0; i < my_arr.length; i++) {
    var val = my_arr[i];
}

for (var i = 0; i < my_arr_length; i++) {
    var val = my_arr[i];
}

for (var i in my_arr) {
    var val = my_arr[i];
}

for ( ; val = my_arr[i++] ; ){

}

for ( i = 0; (val = my_arr[i]); i++ ) {

}

for (i = 0; i < my_arr_length; i++) {
    val = my_arr[i];
}

for (i in my_arr) {
    val = my_arr[i];
}

for ( var i2 = 0, val2 ; val2 = my_arr[i2++] ; ){
