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
Is it actually costly to reassign a function param
<script>
let sum = 0;
function paramReassign(value) {
value = value + 1
return value;
}
function noParamReassign(value) {
const temp = value + 1;
return temp;
}
function noAssign(value) {
return value + 1;
}
function paramReassignAndArguments(value) {
value = value + 1;
return arguments[0]
}
</script>Ready to run.
