One of my developers was a CS grad who took a bootcamp to learn Ruby/Rails. She parlayed that into a $100k job out of the gate doing Ruby/Rails consulting work, and has been one of our top developers ever since. I've talked to her about her bootcamp experience, the main pain points for her were:

- Unsure about whether the cost and time spent were actually worthwhile, or whether self-learning might have been a better option - Bootcamps are not optimized for those who come in with basic programming skills

That second point was also exposed by a close friend of mine who decided to abandon her career in the aerospace/defense industry (she was an aerospace engineer) and do a bootcamp. She was top of our class in college, and she had done a fair amount of basic programming in tools like Matlab. She parlayed her bootcamp experience into a great job as well, but she often found that she was way ahead of the rest of the class. Luckily I've recruited from all of the bootcamps in my town, so I recommended a very good bootcamp with great instructors to her, and her instructors worked to put together a shadow curriculum of work to do while the rest of the class was still working through the main curriculum.

So, YMMV. If you can afford the cost of the bootcamp, it's a proven method to learn new skills and turn that into a new job, but the more programming experience you have, the more you'll find yourself far ahead of the rest of the class.
