I too am a bit confused to why coding bootcamps are needed. I am sure they nicely compress lots of information into a short timeframe but even back in 1997 I was able to teach myself to code simply by sitting at Barnes and Noble reading book after book after book and then trying things out on my own. Today, this should be even easier since it's all online anyway.
If it's too much work looking it up yourself, maybe you don't want to code as much as you think you do.
