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 benchmarks JSON 3 against other JSON implementations.
The following implementations support parsing and serializing:
eval
and a series of validation RegExps.The following implementations only support parsing:
json-parse
: Uses a character-based recursive descent parser.json-parse-state
: Uses a state machine parser.json-sans-eval
: Uses a non-validating RegExp.evalJSON
: Uses a RegExp-based recursive descent parser.<!-- JSON 3 v3.2.6 -->
<script>
// Disable the native JSON implementation.
this.JSON = null;
</script>
<script src="http://cdnjs.cloudflare.com/ajax/libs/json3/3.2.6/json3.min.js"></script>
<!-- JSON 2 -->
<script>
// Set up JSON 2.
this.JSON3 = this.JSON;
this.JSON = null;
