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
Compare localizing a function that needs this context maintained in closure vs lookup every time in foor loop
<script>
var iters = 100;
var testClass = {
exVar: 1,
funcA: function() {
this.exVar + 1;
}
};
var proxy = function(fn, scope) {
if (!scope) scope = this;
return function() {
return fn.apply(scope, arguments);
};
};
</script>
Ready to run.
