It's not much productive to learn RN without understanding JS first. Also, after JS, learning React helps a lot before you learn RN. It's possible to jump to RN directly but again, understaing React will help you understand hooks, functional components, HOCs, blah blah blah... You dont have to be pro to move on to the next step. Just when you think you are comfortable with one, jump to the next one. So for now, understand JS nicely and code a couple projects. Then move to React and complete couple project. Then move to RN and so on. Just my opinion, of course! I've been doing JS and React for couple years now and moved to RN a month ago. Learning React made it possible for me to learn RN in a weekend. So just saying...
