Should You Specialize or Diversify in Programming?

Question

As a programmer, is it better to master one programming language deeply or to have a broad knowledge of multiple languages? Some argue that becoming an expert in one language leads to better job opportunities and deeper problem-solving skills, while others believe versatility across languages makes you more adaptable in different projects.

What do you think? Would you rather be a specialist or a generalist in coding?

Answer 1

at the university we needed to choose a specialization. we still learn more languages....
in my opinion: at least mid-level of 2 languages + some others = you won't be lost if your boss asks you about something. it can a better choice to become a leader.

both are needed, 1 mastered language is not enough in this world

Answer 2

Behaku Awel Negash, there are plenty of specialists, i.e., java developer, c-sharp developer, kotlin developer, go developer, swift developer ... and so on. Yes, they specialize, but they usually know more languages or have some level of familiarity, but their primary choice and knowledge are language oriented.

I'm not saying it's a bad thing, as it's actually good to be language specific as you know the language ins and outs, the limitations, and so forth.

However, it's good to know at least one more language as job opportunities come and go and the need to be flexible in today's marketplace is a must until you can get into the job of your desire.
