It is notable for having a worst case and average complexity of O(n*log(n)), and a best case complexity of O(n) (for pre-sorted input). The basic idea is to split the collection into smaller groups by halving it until the groups only have one element or no elements (which are both entirely sorted groups).

WebFeb 2, 2013 · The practical answer is that currying makes creating anonymous functions much easier. Even with a minimal lambda syntax, it's something of a win; compare: map (add 1) [1..10] map (\ x -> add 1 x) [1..10] If you have an ugly lambda syntax, it's even worse. (I'm looking at you, JavaScript, Scheme and Python.)
