Insert JS code in ionic

Hi, I’m a beginner and intend to make my ionic app.
I have already a html + JS functionnality within my website (a weather forecast presentation based on gps location).
My question is : is it possible to insert it in a easy way to a ionic app ?
Thanks.

If your website is developed in AngularJS then insertion is not that much difficult

thanks ! I’ll try it.
