map

Map an array with an async function

Usage

The map function is like Array.prototype.map, but it works with async functions. Only one item is processed at a time.

const userIds = [1, 2, 3, 4]
const api = {
  users: {
    find: async (id: number) => id < 3,
  },
}

const users = await _.map(userIds, async userId => {
  return await api.users.find(userId)
}) // [true, true, false, false]
