The programming language eco system is exploding. Some very generic and some provide great way to solve a specific domain of problems. On high level, they are all about syntactic sugar to model problems and how its syntax and constructs help solve. I have gone through low level Assembly level to 4th gen (such as SQL) during school and career. At the end, they all are implemented (under the hood) in C/C++ (or other low level procedural language, that comes close to machine language) to convert to machine specific assembly lang (which uses native "instruction set" of the associated CPU).
Srinivas recommends the following next steps:
- Online sites like Youtube, Udemy are great for learning new languages.
- Visit local bookstore and look at the books on available languages. The ones shelved are probably popular :)
