Immutable.js vs Prepack: What are the differences?

What is Immutable.js? 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.

What is Prepack? A tool for making JavaScript code run faster (by Facebook). Prepack is a partial evaluator for JavaScript. Prepack rewrites a JavaScript bundle, resulting in JavaScript code that executes more efficiently. For initialization-heavy code, Prepack works best in an environment where JavaScript parsing is effectively cached.

Immutable.js and Prepack can be categorized as "Javascript Utilities & Libraries" tools.

Immutable.js and Prepack are both open source tools. Immutable.js with 27.8K GitHub stars and 1.61K forks on GitHub appears to be more popular than Prepack with 13.7K GitHub stars and 463 GitHub forks.

    What are some alternatives to Immutable.js and Prepack?
    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.
    jQuery
    jQuery is a cross-platform JavaScript library designed to simplify the client-side scripting of HTML.
    React
    Lots of people use React as the V in MVC. Since React makes no assumptions about the rest of your technology stack, it's easy to try it out on a small feature in an existing project.
    AngularJS
    AngularJS lets you write client-side web applications as if you had a smarter browser. It lets you use good old HTML (or HAML, Jade and friends!) as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly. It automatically synchronizes data from your UI (view) with your JavaScript objects (model) through 2-way data binding.
