altcaps/index.js

Alternating caps, like a myspace teenager from 2001.

#!/usr/bin/env node
module.exports = altcaps
function altcaps(words) {
  const letters = words.toString('utf8')
  const methods = ['Upper', 'Lower']
  var idx = 0
  var midx = (Math.random() * 100)|0
  var newstring = ''
  var letter
  for (; idx < letters.length; idx++) {
    letter = letters[idx]
    newstring += (letter.match(/\s/))
      ? letter
      : letter['to' + methods[midx++ % 2] + 'Case']()
  }
  return newstring
}

  process.stdin.resume()
  process.stdin.pipe(concat(function (data) {
    process.stdout.write(altcaps(data.toString()))
