Ionic in visual 2015

Hello every body,
I am very new to ionic. can any body help me through a good tutorial about app.js, controller.js and template folder . what are they? how can I change them. a book or a website . I use visual studio 2015.

I found that VS 2015 wasn’t handing Typescript well, and I moved to Sublime 3, which is much better. Perhaps VS has since fixed their problems with updates, I don’t know. But I figured you’d want to know my experience.

The Typescript version that comes with Visual Studio installation is not updated.
Make sure you install the latest Typescript version: https://www.microsoft.com/en-us/download/details.aspx?id=48593
