Immutable.js vs Underscore: 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, Underscore is detailed as "JavaScript's utility _ belt". A JavaScript library that provides a whole mess of useful functional programming helpers without extending any built-in objects.

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

"Immutable data structures" is the top reason why over 6 developers like Immutable.js, while over 83 developers mention "Utility" as the leading cause for choosing Underscore.

Immutable.js and Underscore are both open source tools. Immutable.js with 27.6K GitHub stars and 1.6K forks on GitHub appears to be more popular than Underscore with 24.6K GitHub stars and 5.41K GitHub forks.

Pinterest, LinkedIn, and Coursera are some of the popular companies that use Underscore, whereas Immutable.js is used by Instagram, Rove.me, and Broadly. Underscore has a broader approval, being mentioned in 1047 company stacks & 76 developers stacks; compared to Immutable.js, which is listed in 20 company stacks and 11 developer stacks.

Advice on Underscore, Immutable.js

Decided

Fast Healthcare Interoperability Resources (FHIR) provides standard data objects in JSON format for the healthcare industry. Since JSON objects are hierarchical and tree-like, we had a need to defensively 'pluck' fields from our JSON objects and do lots of mapping. We tried jQuery and Underscore and a few other technologies like FHIRPath; but Lodash has been the most well supported, works in the most contexts, has the cleanest syntax, etc. We particularly like the ES6 version of Lodash, where we can import the method names directly, without resorting to * or _ syntax. We got hooked on the 'get' function to defensively pluck fields from objects without crashing our user interface, and have found countless uses for the other lodash functions throughout our apps. Lodash is great for developing and optimizing algorithms.

What are some alternatives to Underscore, Immutable.js?

Deno

It is a secure runtime for JavaScript and TypeScript built with V8, Rust, and Tokio.

Chart.js

Visualize your data in 6 different ways. Each of them animated, with a load of customisation options and interactivity extensions.

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.

Vue CLI

Vue CLI aims to be the standard tooling baseline for the Vue ecosystem. It ensures the various build tools work smoothly together with sensible defaults so you can focus on writing your app instead of spending days wrangling with config.

Luxon

It is a library that makes it easier to work with dates and times in Javascript. If you want, add and subtract them, format and parse them, ask them hard questions, and so on, it provides a much easier and comprehensive interface than the native types it wraps.

Prepack

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.

Blockly

It is a client-side library for the programming language JavaScript for creating block-based visual programming languages and editors. It is a project of Google and is free and open-source software.

Cesium

it is used to create the leading web-based globe and map for visualizing dynamic data. We strive for the best possible performance, precision, visual quality, ease of use, platform support, and content.

Factor

It is an extension-focused and universal Vue.js platform for professional front-end developers. It will help you launch apps that impress and astonish your clients and colleagues. No more re-inventing the wheel, or rewriting and refactoring where it's unneeded.
