Instruction: Which of these programming languages is different from the others : C++, Java, Go, Scala

Response: All these are general-purpose programming languages that are object-oriented. But Scala is the only functional programming language in the list. Scala is built to run on Java virtual machine and has a similar structure as Java. But its use of functional programming constructs makes it more suitable for data intensive and distributed applications.

Most languages in this list support some form of functional programming constructs, but Scala is the only one built with functional programming as a core concept.
