I have been working for web design and some development for almost three years and quite familiar with HTML5, CSS3, an robust Javascript as JQuery.
Now I want to delve into Windows Phone application development since I heard it requires HTML5, CSS3, and Javascript as far as I can understand the development process will be as same as we develop website separate individual files like index.html (for html) .css (for css) .js (for javascript) in a folder.
Do I need other skills and languages or I am on the right path?
