My immediate thought is that you do not need to learn “computer science”.
It is for academics, those looking to differentiate themselves from the other 2000 CS equipped applicants for a job, those wanting interviews answering useless data structure and algorithm questions, and those writing applications in the domains of the computer and data sciences, and computing infrastructure.
Most software is outside of this, though that might surprise many HNs who assume that is the only type of software there is. Well maybe they will cough up “crud apps” if pushed.
Just learn to program and learn the applicable standard libraries associated with a programming language. Stop overthinking it. An 8 year old can do it - you can too.
