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 fn = function(a,b,c,d) {return a+b+c+d;},
obj = {},
fnBound = fn.bind(obj),
fnJsBound = jsBind(obj, fn),
fnStupidBind = rewrite(obj, fn);
function jsBind(self, fn) {
return function() {
return arguments.length
? fn.apply(self, arguments)
: fn.call(self);
};
}
function rewrite(self, fn) {
var f = eval('(' + fn.toString().replace(/this/g, '__this__') + ')');
return function() {
__this__ = self;
var value = f();
__this__ = null;
return value;
}
}
Ready to run.
