kyle-Refactor: Point free with Ramda goodness

point-free-ramda.js.md

The initial function seemed straightforward and very close to functional programming but there was a bit of buried complexity.

function generate(seedWords) {
  const filteredWords = filterInputs(seedWords);
  const initialHash = R.head(filteredWords) || 'thunder';
  const hashWithRandom = appendRandom(initialHash);
  return generateHelper(hashWithRandom, R.tail(filteredWords));
}

The rewrite is point-free and relies on ramda a lot. It isn't highly readable but I think thats because of familiarity with the library and with point free style. The code isn't difficult it's just a bit dense.

const generate = R.pipe(
  filterInputs,
  R.converge(
    generateHelper,
    [
      R.pipe(
        R.ifElse(
          R.isEmpty,
          R.head,
          R.always('thunder')
        ),
        appendRandom
      ),
      R.identity
    ]
  )
)
