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
This test compares the performance of global variables to local variables within functions.
Global variables should be slower because they do not exist in a function's activation object. JavaScript must traverse the Scope Chain to locate global variables.
<script>
function objectCreate() {
return Object.create(null);
}
function objectLiteral() {
return {};
}
function objectNew() {
return new Object;
}
</script>
Ready to run.
