Question

Which is the best language for a computer science student?

Answer 1

It is not possible to learn all languages - in fact there are more than thousands of them.

But probably you will have benefit learning some of them. It depicts the ability of your flexibility and proves that you can work with any technology. Some companies include knowing some languages as a preferred qualification while some are not.

Answer 2

No, you cannot learn them all, and definitely not well. You should pick one based on what you currently want to do, say C# for window/game development, swift for Apple, Kotlin for android, or HTML CSS and JavaScript for the web.
