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
<script type="application/javascript;version=1.8">
"use strict";
function Person(name) {
this.name = name;
const name2 = name
this.get_name_const = function() {
return name2
}
}
Person.prototype.get_name_property = function() {
return this.name;
};
var _c = [];
var i;
for (i = 0; i < 10000; ++i) {
_c.push(new Person('John'));
}
var escape_hatch = null
</script>
Ready to run.
