Hey there, sorry for my late reply. I’m so happy that you enjoyed my talk, it means a lot to me. Thank you!
Like you, I had no prior experience in React before building with React Native. I would dare to say that React Native will actually make you better at React than it would to start the other way around. Some limitations might be that you don’t always get the latest React features in RN and have to wait, but the advantage of working with React Native is that it forces you focus on the fundamentals more.
Anyway, you’re in the same boat as I was starting out, and I would say that will make you better at React over all. Soon you’ll consider React on the web to be rather boring.
