It's funny how the hobby that I had as a kid, which pretty much cost me nothing (aside from the cheap, used, laptop, I bought with my allowance) now makes me more money/year than most people that I know.

I really don't know how a bootcamp can teach you that much in 12 weeks. You might be able to cobble together a couple of react apps, but this will quickly fall apart when you run into problems/issues.
