transformers/filter

transformers/filter :: Function predicate => (Reducer input => Reducer output)

description

Returns a filtering Transformer, which will filter items using the provided predicate, exactly like Array.prototype.filter, but instead returning a decorated reducer. transformers/filter accepts a predicate function and returns another transformer function.

example

basic example

import { filter, transduce } from 'conductor/transformers'

const numbers = [3, 1, 4]
const isEven = x => x % 2 === 0
const add = (acc, value) => acc + value

transduce(filter(isEven), add, 0, numbers) // 4
