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
Testing speed of a standard for loop vs. Array.indexOf.
<script>
var ar=[];
for (var j=0;j<200;j++){
ar.push(parseInt(Math.random(j*123)));
}
var last= ar[199];
function indexOfFor(ar, v){
var l = ar.length;
for(var i = 0; i < l; i++){
if(ar[i] === v){
return i;
}
}
return -1;
}
function indexOfFor_(ar, v){
var l = ar.length;
for(var i = 0; i < l; i++){
if(ar[i] == v){
return i;
}
}
return -1;
}
</script>
