Sammy.js is a tiny JavaScript framework built on top of jQuery for rapid application development. It provides a comprehensive yet manageable set of plugins and functionalities that you can embed in your code to ease the development process.

Sammy is based on a set of integrated plugins and adapters that you can pick and choose to use in your own code as per the desired functionality. Since basic structure of your JavaScript application comes from Sammy, all you have to do is to use the simple API and start building your application. If you already have some structure to start with, just use Sammy as a set of building block to add in your application.

The API is fairly simple and clean. By driving application development around a small and specific API, Sammy helps to keep your code organized while still allowing a lot of breathing room to define your own style and structure.
