funk-lib

FP for Vanilla JavaScript

funk-lib is a standard library for full-stack functional programming with native JavaScript types. It is inspired by Ramda, but does not intend to duplicate Ramda's functionality. There is some overlap with core Browser and Node.js APIs, for the sake of normalization and isomorphism.

Features

Pure functions

Mostly. There are a few documented exceptions

Currying

All functions are curried, and arguments are arranged "data last" for useful partial application

Isomorphic

Packages are available for both

• Node.js (CommonJS) - npm/funk-lib
• Browser (ES Modules) - npm/funk-lib-es

Vast

Includes over 300 functions for working with

• Async (promises)
• Iterables (sync & async)
• Type checking
• Arrays and objects
• Scalars (string, number)
• Function composition
• URLs
• ... and more

For a full list of functions see the Documentation For The Latest Release
