Underscore vs Velocity.js: What are the differences?

What is Underscore? JavaScript's utility _ belt. A JavaScript library that provides a whole mess of useful functional programming helpers without extending any built-in objects.

What is Velocity.js? An incredibly fast animation engine for motion designers. It is an animation engine with the same API as jQuery's $.animate(). It works with and without jQuery. It is the best of jQuery and CSS transitions combined.

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

Underscore and Velocity.js are both open source tools. It seems that Underscore with 24.9K GitHub stars and 5.44K forks on GitHub has more adoption than Velocity.js with 16.2K GitHub stars and 1.53K GitHub forks.

Advice on Underscore, Velocity.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, Velocity.js?

jQuery

jQuery is a cross-platform JavaScript library designed to simplify the client-side scripting of HTML.

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.

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.

Vue.js

It is a library for building interactive web interfaces. It provides data-reactive components with a simple and flexible API.

jQuery UI

Whether you're building highly interactive web applications or you just need to add a date picker to a form control, jQuery UI is the perfect choice.

Svelte

If you've ever built a JavaScript application, the chances are you've encountered – or at least heard of – frameworks like React, Angular, Vue and Ractive. Like Svelte, these tools all share a goal of making it easy to build slick interactive user interfaces. Rather than interpreting your application code at run time, your app is converted into ideal JavaScript at build time. That means you don't pay the performance cost of the framework's abstractions, or incur a penalty when your app first loads.

Flux

Flux is the application architecture that Facebook uses for building client-side web applications. It complements React's composable view components by utilizing a unidirectional data flow. It's more of a pattern rather than a formal framework, and you can start using Flux immediately without a lot of new code.

Famo.us

Famo.us is a free and open source JavaScript platform for building mobile apps and desktop experiences. What makes Famo.us unique is its JavaScript rendering engine and 3D physics engine that gives developers the power and tools to build native quality apps and animations using pure JavaScript.
