Overview

A collection of small, type-safe, performant & immutable iteration utilities for arrays and objects.

# npm
npm i --save @weser/loops

# yarn
yarn add @weser/loops

# pnpm
pnpm add @weser/actions

Because JavaScript's native "functional" APIs such as forEach, reduce, map and filter are slow and limited to arrays only.
There're many different utility packages out there already, e.g. lodash (new tab). But lodash's reduce method itself is 4.5kb gzipped which is way too much for a simple array/object reduce utility.

Additionally, it provides better type inference compared to the built-in methods.
