A good high level overview of the moving parts involved in front end dev is https://roadmap.sh/frontend. Not all of it is used all the time, but if you can talk intelligently about many of the parts you are doing fine.

My recommendation to people learning specific frameworks such as react is to start with vanilla react (their doc's are quite good). Then, after building a small app that solves a problem for yourself, you'll start realising when you have bugs and other maintainability issues related to state management. At that point, it is worthwhile looking into redux (or another state management library). Otherwise if you go straight to react + redux it can just feel like a lot of boilerplate for no reason.

Same with TypeScript. I think type safety offers a huge reduction in the number of bugs in large systems. But it isn't required when first learning react.
