jsPerf.app is an online JavaScript performance benchmark test runner & jsperf.com mirror. It is a complete rewrite in homage to the once excellent jsperf.com now with hopefully a more modern & maintainable codebase.
jsperf.com URLs are mirrored at the same path, e.g:
https://jsperf.com/negative-modulo/2
Can be accessed at:
https://jsperf.app/negative-modulo/2
test the performance of the jquery map versus a native for loop map
<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
testArray = new Array(100);
for(var i = 0; i < 100; i++) {
testArray[i] = i;
}
map = function(array, mapFunction) {
var newArray = new Array(array.length);
for(var i = 0; i < array.length; i++) {
newArray[i] = mapFunction(array[i]);
}
return newArray;
}
double =function(x) {
return x*2;
}
