Thanks!

I would definitely say that this article is a good start. It sounds like you will already have programming fundamentals if you know Python, so at least this article will be useful for syntax.

I’d then move on to reading this: https://medium.com/javascript-in-plain-english/i-created-the-exact-same-app-in-react-and-vue-here-are-the-differences-2019-edition-42ba2cab9e56 as it will show you some React (and also Vue) fundamentals.

Then move on to reading the React docs, which I think are great. Pay particular attention to the React Hooks section, as they greatly simplify state management in React, and massively avoid the need to create and use Class components, which was one of the more difficult things for me to learn when I started with React.

Oh, and finally, be sure to follow JavaScript in Plain English ;)

Hope that helps and best of luck!
