LudoJS is a Javascript framework for rapid development of Web Applications. The framework offers reusable components like grid, trees, lists, form components etc. Ajax is used to populate the components with data. JSON is the main protocol for communication between the server and Client. LudoJS uses the MooTools framework for class/prototype inheritance. The framework offers many layout models which gives you a lot of flexibility on how and where components are rendered on the screen. Example: relative layouts, wizard layouts etc. LudoJS is also great for rapid development of GUI prototypes.
