no-recursion-merge-sort v1.0.1

grin

Simple non-recursive implementation of merge sort. Originally based on this Java implementation, now mostly written by @calvinmetcalf.

Status, should work, does modify the array in place, will not work on sparse arrays exactly like native but that's ok.

Usage

$ npm install grin

Then in code:

var sort = require('grin');
var arr = [3, 2, 1, 4, 10];

// [1, 10, 2, 3, 4]
var sortedNaturally = sort(arr);

// [1, 2, 3, 4, 10]
var sortedNumerically = sort(arr, function (a, b) { return a - b; });

Testing

Unit tests:

$ npm test
