6 best JavaScript Functional programming libraries

JavaScript Functional programming is a Style of programming javaScript applications where the application is structured in a way that it should describe what should happen over defining how it should happen.

With the introduction of the latest JavaScript Syntax, a lot of improvements have been done to boost your JavaScript functional programming workflow, including arrow functions, promises, and the spread operator.

Imagine if you could make JavaScript Functional programming more elegant, and see an instant boost in your workflow.

or even better:

What if there were the 6 best JavaScript Functional programming libraries to choose from.

…and each of them could make your JavaScript development elegant and clean?

You’d probably be pumped to read about them.

Lucky for you, that’s exactly what I’m going to share with you in this post:

6 best JavaScript Functional programming libraries to extend JavaScript’s capabilities.

So let’s get started with the list.

1. Lodash

Lodash is a modern JavaScript utility library delivering modularity, performance, & extras. 

It makes JavaScript easier by taking the hassle out of working with arrays,
numbers, objects, strings, etc. Lodash’s modular methods are great for:

  • Iterating arrays, objects, & strings
  • Manipulating & testing values
  • Creating composite functions

2. Underscore

Underscore is a JavaScript library that provides a whole mess of useful functional programming helpers without extending any built-in objects.

It is a utility-belt library for JavaScript that provides support for the usual functional suspects (each, map, reduce, filter…) without extending any core JavaScript objects.

3. Sugar

Sugar is a library that provides utility functions for working with native objects.

The Sugar global is the main point of interaction, and exposes three different ways of working with the library:

  • Default
  • Chainables
  • Extended Mode

4. Ramda

A practical functional library for JavaScript programmers. Ramda emphasizes a purer functional style.

Immutability and side-effect free functions are at the heart of its design philosophy. This can help you get the job done with simple, elegant code.

Ramda functions are automatically curried. This allows you to easily build up new functions from old ones simply by not supplying the final parameters.

The parameters to Ramda functions are arranged to make it convenient for currying. The data to be operated on is generally supplied last.

5. Lazy.js

Lazy.js is a functional utility library for JavaScript, similar to Underscore and Lodash, but with a lazy engine under the hood that strives to do as little work as possible while being as flexible as possible.

Features

  • Indefinite sequence generation
  • Asynchronous iteration
  • Event sequences
  • String processing

6. Mout

The purpose of this library is to provide modular solutions for common problems that aren’t solved by most of them. Consider it as a cross-browser JavaScript standard library.

Pros of Using this Library

  • increase code reuse;
  • be clear (code should be clean/readable);
  • be easy to debug;
  • be easy to maintain;
  • follow best practices;
  • follow standards when possible;
