Best JavaScript Utility Libraries

In this article, I would like to suggest a few best Javascript utility libraries that are useful and highly maintained libraries. The source code of these JavaScript libraries hosted and maintained on GitHub.

1. Underscore -

Underscore is a JavaScript library that provides a whole mess of useful functional programming helpers without extending any built-in objects. It’s the answer to the question: “If I sit down in front of a blank HTML page, and want to start being productive immediately, what do I need?” … and the tie to go along with jQuery's tux and Backbone's suspenders.

2. Lodash -

A modern JavaScript utility library delivering modularity, performance & extras. Lodash, NPM’s most downloaded and most dependent-upon package, was built to provide more consistent cross-environment iteration support for arrays, strings, objects, and arguments objects.

3. MathJs -

Math.js is an extensive math library for JavaScript and Node.js. It features a flexible expression parser with support for symbolic computation, comes with a large set of built-in functions and constants, and offers an integrated solution to work with different data types like numbers, big numbers, complex numbers, fractions, units, and matrices. Powerful and easy to use.

4. Moment -

A lightweight JavaScript date library for parsing, validating, manipulating, and formatting dates.

5. Sugar -

Sugar is a Javascript utility library for working with native objects.

6. Lazy -

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.

7. CollectJs -

CollectJS is one of the dependency-free wrappers to work with array and objects in the javascript.

8. Ramda -

A practical functional library for JavaScript programmers.

9. VOCA -

Voca is a JavaScript library for manipulating strings.

You can suggest if you have any useful JavaScript library in the comment section.

I hope this short list of JavaScript utility libraries useful to you.
