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
Whether it is faster to call() a Function (Function.call), or pass context as argument (Function(arg))
var fA = function(body) {
return Function("with(this) { return (function(){" + body + "})(); };")
}
var fB = function(body) {
return new Function("a", "with(a) { return (function(){" + body + "})(); };")
}
var targ = "var a = 1;"
Ready to run.
