Variable: findConcur

const findConcur: FindConcur

Defined in: filters.d.ts:764

Returns a concur iterable containing the first value of concurIterable for which fn returns a value awaitable to a truthy value. Otherwise, returns an empty concur iterable.

Like Array.prototype.find, but for concur iterables.

Example​

import { asConcur, findConcur, orConcur, pipe } from 'lfi'

const API_URL = `https://api.dictionaryapi.dev/api/v2/entries/en`
const getPartsOfSpeech = async word => {
  const response = await fetch(`${API_URL}/${word}`)
  const [{ meanings }] = await response.json()
  return meanings.map(meaning => meaning.partOfSpeech)
}

console.log(
  await pipe(
    asConcur([`sloth`, `lazy`, `sleep`]),
    findConcur(async word => (await getPartsOfSpeech(word)).includes(`verb`)),
    orConcur(() => `not found!`),
  ),
)
// NOTE: This word may change between runs
//=> sloth

console.log(
  await pipe(
    asConcur([`sloth`, `lazy`, `sleep`]),
    findConcur(async word => (await getPartsOfSpeech(word)).includes(`adverb`)),
    orConcur(() => `not found!`),
  ),
)
//=> not found!
