Ext JS

What do you like best?

The choice of widgets. The framework is really feature rich and has all the components that you might need as a developer like windows, panels, grid, tables, message boxes, forms and dynamic charts.

The UI framework is very rich and well integrated and makes it very easy to deal with lot of Ajax functionalities out of the box.

What do you dislike?

The license for using the dynamic charting components is prohibitively expensive. The free version comes with limited support and sometimes you need to write your own code just to fix Ext JS release bugs.

What problems are you solving with the product? What benefits have you realized?

UI Development - We provide a feature rich and highly responsive UI to our users and availability of interactive UI components is a must. The Ext JS components like grids and panels make that job easier and provide users with a fabulous UX experience.
