A Javascript fizzbuzz which is entirely functional and does not contain any of the following as substrings: for, while, if, else, return.

fizzbuzz.js

const fbGen = (fbValues, min, max) =>
  Array.apply(null, Array(max - min + 1))
    .map((val, i) => min + i)
    .map(val =>
      fbValues.reduce(
        (accum, fbVal) =>
          val % fbVal.number === 0 ? `${accum}${fbVal.text}` : accum,
        ''
      ) || val
    )
    .join('\n')

const fizzbuzz = fbGen(
  [{ number: 3, text: 'Fizz' }, { number: 5, text: 'Buzz' }],
  0,
  100
)

console.log(fizzbuzz)
