Benchmark: For Loop vs While Loop vs indexOf

Script Preparation code:

var arr = ['apple', 'banana', 'cherry', 'donuts', 'eggplant', 'french fries', 'goulash', 'hamburger', 'ice cream', 'juice', 'kebab', 'lemonade', 'mango', 'nuts', 'octopus', 'parsley', 'quail egg', 'risotto', 'stew', 'tapas', 'udon', 'vanilla', 'wheat', 'xylotil', 'yogurt', 'zucchinni'];

function forLoop(array, item) {
	for (var i = 0; i < array.length; i++) {
    	if (array[i] === item) {
          return i;
        }
    }
    return -1;
}

function whileLoop(array, item) {
  	var i = 0;
	while (i < array.length) {
    	if (array[i] === item) {
        	return i;
        }
      	i += 1;
    }
    return -1;
}

function indexOfNative(array, item) {
	return array.indexOf(item);
}
