console.log(
  await pipe(
    asAsync([`sloth`, `lazy`, `sleep`]),
    flatMapAsync(async word => {
      const response = await fetch(`${API_URL}/${word}`)
      const [{ meanings }] = await response.json()
      return map(meaning => meaning.partOfSpeech, meanings)
    }),
    takeWhileAsync(partOfSpeech => partOfSpeech.length === 4),
    reduceAsync(toArray()),
  ),
