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
const s = Symbol('a')
class A {
constructor(x) {
this.x = x;
}
}
class B {
constructor(x) {
this.x = x;
this.y = s;
}
}
function isA(x) {
return x instanceof A;
}
function isB(x) {
return x.y === s;
}
function isC(x) {
return { y: s }
}
function isD(x) {
return !!x[s];
}
Ready to run.
