-- Haskell filter even [1,2,3,4]

• T_S_ 16y ago
  Or take 2 (filter even [1..]) // take as many as you want

    This is true, I forgot to mention that the haskell version trivially scales to infinite lists. You can use partial application to encourage code reuse as well: evens = filter even

      Even better.

    I'm currently in the process of learning it, and I'd definitely recommend it. If nothing else, it's great having a compiler that can catch a large amount of errors without getting bogged down in the type boilerplate that many other static languages require. Implicit static typing is definitely something I miss when working in other languages.

  Save some characters: filter even [1..4] I've found most of the time when you're trying to get incredibly short expressions that aren't obfuscated, haskell wins.
