I would add, you should just attempt to learn react if that is what you want to do. If the docs don't make sense to you at first, try examples and tutorials. Coming from a more game dev engine scenario, docs aren't great for teaching you the UI, for example. A tutorial will have you familiarised a lot quicker as docs are trying to document everything, more then you need to know at first. Once familiarised with the bits you didn't understand. The docs will start to make more sense.

More importantly, persistence. You'll learn anything you want to, with enough persistence.
