The needs of customers are constantly changing with the evolution of devices. WinJS provides a way to make it easy to create responsive apps that not only work across all screen sizes, but also with all input methods.

Industrial strength ListView – Some of the best-in-class controls like ListView provides native performance and supports an extensive set of app scenarios. New features like striping, headers and footers, and improved selection have been a great value-addition.

WinJS 4.0 will emphasis on providing great app experiences. Microsoft believes that great responsive design should not only work for all screen sizes but also with different input types – keyboard, mouse, touch etc. WinJS has been designed keeping the above app experience aspects in mind.
