Every programming language has its strengths and weaknesses. After having achieved an understanding of the theory of programming languages it becomes easier to adapt and quickly learn new ones, with a bit of practice. There are always going to be some programming languages that are more popular in industry verses others that are more used academically. With a bit of pragmatism one can work out when to use which language and treat it as a dispensable tool. When new programming constructs and dialects evolve, out of research, to reduce the increasing dynamic changes in system and application complexity, it equally becomes paramount to keep one's language skills up-to-date. The below list provides the current popularity in programming languages that are most used in industry and those that could potentially be the next ones on a programmer's radar for learning.
