Simple utility function for "pipe-ing" values into functions because JavaScript doesn't have a Pipe (forward) operator... yet.

pipe.js

// Utility Function Definition
// A pipeline will call a series of functions pipe-ing output to input.
function pipe () {
  return [].slice.call(arguments)
    .reduce(function (acc, fn) {
      return fn(acc)
    })
}

// The above code compresses better then the ES2015 version.
// const pipe = (...arg) => args.reduce((acc, fn) => fn(acc))
// ... not to mention, this doesn't as gracefully accept multiple arguments
// e.g. pipe([1, 2, 3], fn, fn, fn)

// Example
const result = pipe(
  [1, 2, 3, 4, 5, 6],
  (args) => args.reduce((a, b) => a + b),
  (result) => result * 2,
  addWord('is the answer to the ultimate question of'),
  addWord('Life'),
  addWord(', The Universe'),
  addWord('and Everything.'),
)

// result = '42 is the answer to the ultimate question of Life , The Universe and Everything.'
