Everyone's a newbie at some point - but just because you're a novice doesn't mean that you can't benefit from veteran knowledge. Bootcamp curriculum is developed to put you at the forefront of the industry - you'll be learning the newest languages and skills that will best prime you to capitalize on the most relevant job opportunities.
The idea of learning new skills is so exciting - but "shiny object syndrome" is real. With so much to learn, and so many directions to go in, it's easy to become distracted and overly-focused on the wrong things. Bootcamps keep you in line and focused on solid goals, which turn into portfolio projects in the future.
