Have you ever tried lodash/fp? It comes with all the same functions, but they are curried and none of them mutates the input.

Because of that, you can compose them in a really nice way.

Example:

import moment from 'moment'
import { compose, filter, groupBy, size, sortBy } from 'lodash/fp'

const fromAdmin = filter({ type: 'admin' })
const groupedByDate = groupBy(message => moment(message.createdAt).format('YYYYMMDD'))
const sorted = sortBy('createdAt')
const unreadByUser = filter({ isReadByUser: false })

const groupedMessages = compose(
  groupedByDate,
  sorted,
  unreadByUser,
  fromAdmin,
)(messages)
