Will it help you learn? Absolutely.
Will it help you get a job? Possibly but far from a garuntee.
When recruiters and hiring managers see that skill on your resume, they will ask when you have used it in an enterprise environment. You will say never, and it will greatly devalue the skill... even if you are really good at it. Personal coding and enterprise dev work have very little in common.
However its not all doom and gloom. You can use that knowledge and create a portfolio. Make a github repro and put personal projects there. Once again thats not too similar to enterprise work but it gives them something tangible to say "oh.. he does something"
Its 2019, as a developer you should have an online portfolio and a link to it in your CV, bootcamps can at least give you knowledge to do so.
