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
var slice = Array.prototype.slice;
or var slice = [].slice;
?
(Benchmark.prototype.setup = function() { }).toString = function() {
return [
'// 1 deep',
'(function() {',
' // 2 deep',
' (function() {',
' // 3 deep',
' (function() {'
].join('\n');
};
(
}).toString = function() {
return [
' }());',
' // end 3',
' }());',
' // end 2',
'}());',
'// end 1'
].join('\n');
Ready to run.
