Small utils that bring great satisfactions

farrapa packages just bring some low level, not crucial but usual tools you may need. At least we need them!

Tools are split in different import paths. So your bundle size won't be affected.

For example:

import {collTotalBy} from 'farrapa/collections'

const people= [
  {'name': 'Peter', 'age': 27},
  {'name': 'Lillah', 'age': 32},
  {'name': 'Freddie', 'age': 41},
]

const total = colLTotalBy(people, 'age')

// 100
