Velocity.js

What do you like best?

For a front end developer looking for a stand-alone animation library, this is the best option. It can interop with JQuery (and other front end frameworks) very nicely, and heavily reduces complexity for animation-heavy projects like social hubs and complex widgets. When you do not want to spend hours debugging widget animations, it is nice knowing velocity will just handle it for you.

What do you dislike?

I wish there were multiple installation candidates. Compartmentalized libs that offer a single animation tool would make velocity JS usage less painful on smaller widgets. While velocity supports nearly every front end framework on the block, some frameworks already offer their own in-house animation library that is usually preferred over velocity.

Recommendations to others considering the product:

Check you front end framework docs first to see if it already has a preferred way of implementing animations.

What problems are you solving with the product? What benefits have you realized?

I use velocity JS to quickly develop animations for one-off single page applications. It greatly reduces dev time for high-interactivity widgets, and is easy enough to install that you can rapidly strut out a small client project with it.
