fn

Functions for your higher-order functions.

Installing

npm install fn

Usage

  var fn = require('fn');

  var thirdChars = ['one', 'two', 'three'].map(fn.at(2)); // ['e', 'o', 'r']
  var lastChars = ['one', 'two', 'three'].map(fn.last()); // ['e', 'o', 'e']
  var keys = [{ a: 1, b: 2 }, { c: 3 }].map(fn.keys()); // [['a', 'b'], ['c']]

The functions at, last and keys are only a few of the available ones. Until there's a more complete list in the docs, please look at the source. It's quite easy to get what functions there are.
