Benchmark: loop direct vs with result checks

Script Preparation code:

function aLoop(obj, fn){
	for (var i=0, len=obj.length;  i<len;  i++){ fn(obj[i], i, obj); };
}
function returnLoop(obj, fn) {
	for(var result,i=0,len=obj.length;  i<len;  i++){
		if((result=fn(obj[i], i, obj))) return result;
		if(result!==undefined) break;
	};
}
var smallObj = [1,2,3];
var largeObj = [1,2,3,4,5,6,7,8,9,10,11,22,33,44,55,66,77,88,99,123,124,125,156,127,128,129,134,135,136,137,138,139,145,146,147,148];

Tests:

loop direct - smallObj
aLoop(smallObj, function(elm) { //return ''; });
loop direct - largeObj
aLoop(largeObj, function(elm) { //return ''; });
loop with result checks - smallObj
returnLoop(smallObj, function(elm) { //return ''; });
loop with result checks - largeObj
returnLoop(largeObj, function(elm) { //return ''; });
