There is a project TodoMVC which implements the same Todolist application in different frameworks, check http://todomvc.com/ They have sources in GitHub https://github.com/addyosmani/todomvc I think it could be nice if NetBeans offers HTML5 sample projects like "TodoMVC - AngularJS" or "TodoMVC - Backbone.js" etc. that should be downloaded from GitHub the same way current HTML5 samples are. This could give users easy way to test different JS frameworks in NetBeans
