Supersonic vs Zepto: What are the differences?

Supersonic: UI Hybrid Framework – Ionic, AngularJS, Cordova. Supersonic UI is a game-changer. It's an Ionic fork that changes the way you think about hybrid app performance. Supersonic's declarative UI style makes building complex mobile apps a breeze. In the background, the seamless interplay of native UI and HTML5 bakes an end-result that is 100% indistinguishable from any native app; Zepto: Minimalist JavaScript library for modern browsers, with a jQuery-compatible API. While 100% jQuery coverage is not a design goal, the APIs provided match their jQuery counterparts. The goal is to have a ~5-10k modular library that downloads and executes fast, with a familiar and versatile API, so you can concentrate on getting stuff done.

Supersonic and Zepto can be categorized as "Javascript UI Libraries" tools.

Some of the features offered by Supersonic are:

• Mobile-first CSS components
• Native UI components, with CSS styling
• Declarative UI
