React - Is There Anything You're Having Problems With?

When I first learned react, my tendency was like,  I should learn how to actually write this library. And as I'm using it really understand like vanilla JavaScript really well and then kind of see those come together. It's probably a pretty good way of thinking to like write the library, but I think I've heard before someone say like, okay, someone who makes the car versus someone who's drives the car. So like, I guess it's good to have like sort of both, but like you need to know how to drive it,. If you know how to make it, if you don't know how to use it, you may not know how to driving it.
