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

Run if exists or run empty

Benchmark created by Anderberg on October 23, 2014

Description

Is checking if a function exists before running it faster than simply running an empty function?

Setup

function Omg () {}
    Omg.prototype.empty = function () {};
    
    var o = new Omg();

Test runner

Ready to run.

Testing in
Test		Ops/sec
If function	`if (o.empty2) { // Does not exist o.empty2(); }`	ready
Empty function	`o.empty();`	ready
