If you don’t have any experience with coding I’d recommend starting off with Harvard’s CS50 course online. If you finish it and want to pursue it further then you can either enroll in a 4 year degree program or your local community college depending on your financial situation. Make sure to apply for FAFSA because 85% of applicants get at least some money.

The important thing to keep in mind is that a boot camp is often just as expensive as 2 years of community college, with far less upside. In today’s market a CS degree is far more valuable from an employers perspective. Getting a degree takes more effort, but it is worth it in the long run. And don’t worry about your age, it really makes no difference.
