An object-oriented JavaScript framework

Improved is a JavaScript framework that aims to ease development of dynamic web applications. It offers a familiar class-style OO framework, extensive Ajax support, higher-order programming constructs, and easy DOM manipulation. Improved has been derived from the Prototype Javascript Framework initiated by Sam Stephenson.

  • Chrome 6 and higher
  • Apple Safari 3 and higher
  • Mozilla Firefox 2 and higher
  • Microsoft Internet Explorer for Windows, version 6 and higher
  • Opera 10 and higher
