ease.js is a collection of CommonJS modules intended to “ease” the transition into JavaScript from other Object-Oriented languages. It provides an intuitive means of achieving classical inheritance and has planned support for traits/mixins, function overloading and more.
ease.js is a framework. It is not a compiler. This allows you to use it wherever JavaScript may be used, including with other compilers/parsers. It provides support for older, pre-ES5 browsers by gracefully dropping features (such as visibility), but remaining functionally consistent. Therefore, code written using ease.js should operate exactly the same in Internet Explorer 5.5 as it does in Chromium 10.
This project is under heavy development. However, the master branch is always guaranteed to be in a working, stable state. It is currently in use within a production system at the author's place of employment. Feel free to use ease.js in your own projects.
