Overview

Awesome Functional Programming in JavaScript is a curated GitHub directory of libraries, tools, and learning resources for doing functional programming (FP) in JavaScript. It helps developers use JavaScript’s functional features more effectively by collecting FP-focused code, articles, books, and examples in one place.

Features

Core Focus

• Curated list specifically dedicated to functional programming in JavaScript.
• Emphasis on side-effect free functions, immutable data, and expression-based code.
• Aimed at using JavaScript’s multi-paradigm capabilities in a functional style.

Library Directory

• Collection of functional programming libraries for JavaScript.
• Includes common FP constructs such as:
  • pipe()
  • Maybe
  • Result
• Tagging system for entries, allowing annotations like:
  • -TS (likely indicating presence/absence of TypeScript typings)
  • -CT (another filter tag mentioned in the list)
• Tags are designed to help filter libraries for specific needs (e.g., TypeScript users).

Data Structures

• Section dedicated to functional data structures for writing performant FP-style code.
• Focus on choosing the right structure to enable efficient and idiomatic functional patterns.

Algebraic Data Types (ADTs)

• Section covering algebraic data types and related concepts, including common variants:
  • undefined
  • null
  • Either
  • Maybe
  • Result
  • Ok
  • Err
• Encourages using mathematically grounded abstractions instead of ad-hoc designs.

Lenses

• Section for lenses and related optics tools for immutable data manipulation.

Functional Languages that Compile to JavaScript

• Directory of functional-first languages and projects that compile to JavaScript.
• Useful for exploring FP beyond plain JS while still targeting the JS ecosystem.

Programming Tools

• Section for developer tools that support or enhance functional programming workflows in JavaScript.

Learning Resources

Books

• Curated list of books on functional programming concepts and their application in JavaScript.

Articles

• Collection of articles covering FP patterns and abstractions in JS.
• Mentions topics/constructs such as:
  • Maybe
  • Either
  • Validation

Videos

• Section for video resources (talks, lectures, tutorials) on FP in JavaScript.

Examples and Exercises

• Practical section with examples and exercises demonstrating FP techniques such as:
  • map
  • filter
  • concatAll
  • reduce
  • zip

Community & Meta

• Contribution guidelines for adding new libraries and resources.
• Code of conduct file in the repository to define community expectations.
• Related lists section pointing to other curated collections in the broader FP ecosystem.
• Talk section for references to conferences or presentations related to FP in JS.

Pricing

• This is an open-source GitHub repository and curated list.
• Cost: Free to access and use.
