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:

pop vs shift on a array (v30)

Revision 30 of this benchmark created on April 25, 2014

Description

If you can choose between a .pop() or .shift() on a Array, what would be a wise decision?

As my http://jsperf.com/adding-items-array/6 test shows the unshift is awful for performance. The same counts for .shift(), awful performance.

Test runner

Ready to run.

Testing in
Test		Ops/sec
.pop()	`var array1 = new Array(2000); array1.pop();`	ready
.shift()	`var array1 = new Array(2000); array1.shift();`	ready
