Kind of a lie, BWAHAHHAHAHAHAHAHAHAHAHAHAAAAAAAAAAAAThat last part about cobol is kind of a lie, like you do still see the remnants of cobols code everywhere but I don't think anybody is looking for it. When I've seen postings specifically mentioning cobol, those jobs are underpaying by a significant margin compared to a junior dev or a full stack developer. This probably doesnt apply to everyone, but where I live in the US, if you want to get a job as a programmer you need to be a "full stack developer" which is a really broad term for knowing some front end and some back end. Most "Full stack" developers arent full stack devs at all. It boils down to knowing multiple languages and learning whatever the rotating flavors are.
A lot of people have different experiences with it but this is generally what employers want. My info might be dated since I haven't payed attention in like 2 years and was never interested in becoming a dev to begin with but this is my understanding
Front end:
HTML, CSS, JavaScript(using nodejs) and experience in mongoDB
Back End:
Python/django, Java, PHP, Go, Ruby, C#
Half of the languages I've listed I don't know but have used. For example, I've never learned php but I have had to look at its documentation and write scripts in it to interact with applications. Other languages are useful, but not practical, and are usually extra requirements for some niche thing. The last job I looked at that fit closer to my skills was a company wanting to write an OS for a plane and looking for low level programmers (low level means languages that are closer to bare metal binary). Every business can use those front end and back languages, only people around enterprises and hobbyists use anything lower than the fullstack languages I listed.
Otay A quick DDG search says otherwise but we'll go with kind of a lie just cause.
Anyway, I posted links to some sites that basically tell you (not the person I'm quoting) which languages are in demand and/or are on their way up. Kind of startling to see C++ getting wheedled out but I THINK it's because of all the "studio" applications (think rpgmaker or even one of the mod making apps like the GECK for fallout) that probably use it. Don't know, it's actually been a while since I've done any real programming. Once I could afford it I started paying other people to do that. AND everything I did know what self taught and researched and borrowed books from the library. I started my business on the back of library books and nudes of friends. I think I'm rambling, Nevermind.
