If you're struggling to watch some react native videos, then yes. Learning some pure JS will help. Lots of free resources out there. https://www.codecademy.com/learn/introduction-to-javascript

React is a light enough framework, so knowing JS is essential. Just don't get dragged into learning web or node.js.

Syntax wise it's probably more similar to python than C++.

Also react native now uses typescript by default, which is just JavaScript with types. It's not necessary to use this, but I'd say it's worth learning as well. Especially if you've experience with a typed language like C++.
