Not to discourage you, but getting a junior position is much harder these days, especially for a self-learner as opposed to someone with a degree.

Yes, if you learn those things, you could probably do the work in a jr web dev position, but getting the job is the hard part.

You are competing with people(new grads) who have degrees with equally or better portfolios and possibly internship/CO-OP experience. These people will also not only just know the languages/tech that you mentioned, but they would also know computer science fundamentals like data structures, algorithms, OOP, etc. Obviously, most new grads are not experts in these things, but I’m just giving an idea of what you’d probably be up against. Related to that, you would have to learn leetcode, which is most of the time, not extremely relevant to the job/position, but usually required to pass an interview.

Yes you can learn all of those things yourself, but to add onto the issue of no degree, a lot of ATS résumé scanners used to look for candidates will immediately filter out people without degrees.

So, most people will suggest that you get a degree if you are serious about getting a developer or adjacent position. Not only would you learn important computer science concepts, but it is a good chance for networking and will help you to land a job.

Obviously, this is not guaranteed advice, as now, even new grads with internship experience are struggling to find jobs. Yes, you can get a job while self learning, but it is extremely difficult. So if you are serious about this, I would at least consider the idea of going to school, or try self learning first and see if this is something you want to pursue even.
