Is Learning One Programming Language Adequate Any More?

In order to be a good developer, it did not take too long time to mean to devote oneself to one language, C++, Java or PHP, etc. After learning one, then you would be able to build your whole career on it.

The present technological setting is saying otherwise. Frameworks, cloud platforms, DevOps practices and even AI-assisted code are all meant to enable developers to migrate more than ever across an ever-growing set of languages and ecosystems.

For you to think,

• APIs may be written in Node.js by a backend engineer, but Python may be needed on data pipelines.
• The frontend should be in JavaScript or TypeScript although the backend code might be in PHP or Laravel.
• There is hardly a single lane where mobile developers can be fitted. Among them are Kotlin, Swift, Flutter and React Native.
• The basics will remain, though- algorithms, databases, networking and version control are the sticks that enable the learning of new tools and languages to become much easier.

So here’s the big question:

In the contemporary frenzied world of the industry, is it more appropriate to deep dive into a single language and concentrate on it and specialize in it or is it more appropriate to diversify and become a master of several languages?

I believe that experience makes experience, and you are most convenient in the specialized departments. Other individuals believe that the best approach is to go with the breadth and you can have another role, or another team or project to work on.

Where are you, and what has been your personal experience as a career or in learning affected your viewpoint?
