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 m = new Int32Array(1024);
m[0] = 1;
sp = 1;
var fibTyped = function fib(x) {
sp += 2;
if (m[x] < 4) return 0;
m[sp - 2] = m[x] - 2;
m[sp - 1] = m[x] - 1
var t = fib(sp - 2) + fib(sp - 1);
sp -= 2;
return t;
}
var fibNomal = function fib(x) {
if (x < 3) return 1;
return fib(x - 2) + fib(x - 1);
};
var fibAsmjs = (function () {
'use asm';
function fib(x) {
x = x|0;
if ((x|0) < 3) return 1;
return ((fib((x - 2)|0)|0) + (fib((x - 1)|0)|0))|0;
}
return fib;
})();
