Immutable.js vs Polly.JS: What are the differences?

Developers describe Immutable.js as "Immutable persistent data collections for Javascript which increase efficiency and simplicity, by Facebook". Immutable provides Persistent Immutable List, Stack, Map, OrderedMap, Set, OrderedSet and Record. They are highly efficient on modern JavaScript VMs by using structural sharing via hash maps tries and vector tries as popularized by Clojure and Scala, minimizing the need to copy or cache data. On the other hand, Polly.JS is detailed as "Record, replay, and stub HTTP interactions". Polly.JS is a standalone, framework-agnostic JavaScript library that enables recording, replaying, and stubbing HTTP interactions Polly taps into native browser APIs to mock requests and responses with little to no configuration while giving you the ability to take full control of each request with a simple, powerful, and intuitive API..

Immutable.js and Polly.JS can be primarily classified as "Javascript Utilities & Libraries" tools.

Immutable.js and Polly.JS are both open source tools. It seems that Immutable.js with 27.8K GitHub stars and 1.61K forks on GitHub has more adoption than Polly.JS with 7.75K GitHub stars and 219 GitHub forks.

    Lodash
    A JavaScript utility library delivering consistency, modularity, performance, & extras. It provides utility functions for common programming tasks using the functional programming paradigm.
    Ramda
    It 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.
    JavaScript
    JavaScript is most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic,and supports object-oriented, imperative, and functional programming styles.
    Git
    Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.
