Post #274,265 by tuberculosis 11/28/06 7:19:27 PM Reply	Smalltalk queries/collection operations predate SQL by about 5 years I think. Smalltalk collections respond to: select: - provide filtered version of collection ie #( 1 2 3 4 5 6 ) select: [:each \| each isEven]. #(2 4 6) detect: - first found #( 1 2 3 4 5 6 ) detect: [:each \| each > 3 and: [each isOdd]]. 5 reject: - inverted select #( 1 2 3 4 5 6 ) select: [:each \| each isEven]. #(1 3 5) collect: - used to derive a new collection from an existing one #( 1 2 3 4 5 6 ) collect: [:each \| each * 5]. #(5 10 15 20 25 30) Nothing to reinvent, really. We were here first.

Post #274,708 by ChrisR 12/3/06 7:24:49 PM 12/3/06 7:28:35 PM Reply	Some context... Map, Filter, and Reduce are morphisms arising from mathematics. Likely that if you want to find the first use in programming languages, you'd probably find them in Lisp. But then Smalltalk was heavily influenced by Lisp (and Algol), so that wouldn't be surprising. Map applies a function over a collection. Filter applies a predicate to a collection and returns a subset where the predicate is true. Reduce is a fold of a collection. Guess I should also reuse my explanation of [link\|http://z.iwethey.org/forums/render/content/show?contentid=247589\|Higher Order Functions] in an earlier thread.
