Porting angular project to ionic 2

I have 2 questions about his in particular. Can an angular project be ported to ionic 2? it’s written with angular 1 and my second question is does it matter that it’s written in javascript rather than typescript? I appreciate any responses I get

Porting an angular 1 app to ionic 2 requires some work. You’ll eventually be rewriting your app to fit angular 2 and ionic 2.
