Fast, modern, and practical utility library for FP in TypeScript.
- 👀 provides more readable code, due to the
data-firstapproach - ✨ supports
TypeScript - 🛡 helps you write safer code with
MaybeandEithertypes - 🎯 all functions return immutable data (no side-effects)
- 🌲 tree-shakeable

import { pipe, Maybe, Arr } from 'lambda-craft'
const r = pipe(
Arr.of(1, 2, 3, 4, 5), // -> [1,2,3,4,5]
Arr.take(2), // -> [1,2]
Arr.find(n => n == 1), // -> Maybe(1)
Maybe.map(n => n * 10), // -> Maybe(10)
Maybe.getOrDefault<number>(5), // -> 10
