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
var elementToCheck = 500;
var ar = [];
var arrayLength = 1000;
while( arrayLength-- >= 0) {
ar.push(arrayLength);
}
function fastIndexOf(arr, search) {
for(var i = 0; i < arr.length; i++) {
if(arr[i] === search) {
return i;
}
}
return -1;
}
Ready to run.
