What Hacker News says

This is part of the reason why I ported Vladimir Yaroslavskiy's dual-pivot quicksort to JavaScript (https://github.com/square/crossfilter/blob/master/src/quicks...) for Crossfilter (http://square.github.com/crossfilter). It is much, much faster than the native sort. I would guess that WebKit uses this slower algorithm because it's an easy way to implement stable sort. If I recall, Chrome was one of the earlier browsers to implement a non-stable sorting algorithm for JavaScript and it broke various pages that assumed stable sort (such as tables that let you sort by multiple columns). Fun side-note: you can use a matrix diagram to visualize how your browser sorts, letting you determine your browser's sort algorithm visually. For example, Chrome uses median-of-3 quicksort, and Firefox uses mergesort. See for yourself! http://bost.ocks.org/mi
