Interactive Rating Component Vanilla JS

Thanks for viewing my code!

This is my first project and I really struggled with many aspects of it.

I'm wondering if my code is up to snuff for this project. I feel like I have a lot of redundant code in my text. Are there any better ways to complete this project? My biggest issue that I had was that I wanted to add a transition effect that would fade in my .thanks container but I couldn't get it to work in the long run. Most of the ways that I found to do it in Vanilla JS, I couldn't wrap my head around and it's easier with JQuery but I don't have any experience with it yet. Thank you all for reading!
