Description

This class extends the normal Array adding the following async methods:

  • everyAsync
  • filterAsync
  • findAsync
  • findIndexAsync
  • includesAsync
  • someAsync
  • mapAsync
  • reduceAsync
  • reduceRightAsync

Use cases

This methods can be useful in a lot of cases, for example you can use map to transform an array of urls, in an array of documents :

const asyncListOfUrls = AsyncArray.from(listOfUrls)
const asyncListOfDocuments = await asyncListOfUrls.map(downloadUrl)

or a long list of user cases ( this are just examples ):

const asyncListOfFilenames = AsyncArray.from(listOfFilenames)
const asyncListOfSmallFiles = await asyncListOfFilenames.filter(isFileSmallerThan300KB)
const asyncListOfDependecies = AsyncArray.from(lListOfDependecies)
const isAppUpdated = await asyncListOfDependecies.every(isDependenciesUpdated)
