Benchmark: Array loop - MeasureThat.net

Script Preparation code:

var loopItems = [];
var i = 0;

for (i = 0; i < 1000000; i++) {
	loopItems.push(Math.random());
}

var process = function (i) {
	i++;
}

Tests:

Standard For loop i++
i = loopItems.length; for (var j = 0; j < i; j++) { process(loopItems[j]); }
Standard For loop i--
i = loopItems.length; for (var j = i; j > 0; j--) { process(loopItems[j]); }
While, i--
i = loopItems.length; while (i) { process(loopItems[i--]); }
While, with 8 iterations, with function call
i = Math.floor(loopItems.length / 8); while (i) { process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); }
While, with 8 iterations, without function call
i = Math.floor(loopItems.length / 8); while (i) { loopItems[i--]++; loopItems[i--]++; loopItems[i--]++; loopItems[i--]++; loopItems[i--]++; loopItems[i--]++; loopItems[i--]++; loopItems[i--]++; }
While, with 50 iterations, with function call
i = Math.floor(loopItems.length / 50); while (i) { process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); process(loopItems[i--]); }
