Introsort implemented in Javascript

Javascript implementation of Introsort.

There are probably not many real-world use cases for it judging by this JSperf benchmark, but I was Googling and couldn't find a Javascript version of this algorithm.

I found this Java version and ported it over to Javascript

Install using npm:

npm install introsort


var introsort = require('introsort');
var array = [5,3,9,292];


  • I noticed that it does not sort correctly if the array contains zeros. Probably something wrong in my port (at least trailing zeros)
  • The whole thing can probably be optimized a lot for Javascript. The straight up Java port is probably not the fastest way to go
