Answer 2

Hello, Rishi Raj Singh !
It all depends on the task that you want to solve. However, if this is your first language, I would recommend a strongly typed general-purpose language (C++, Java, .NET): with them, in any case, do not disappear and it will be easy to switch to any other language. Another interesting way to understand what language to take to study - go to GitHub, enter into the search of the topic of interest and see what other developers write.
