Identify any eight new programming languages and classify them based on their functionality.
shepuryov [24]

Answer:

Some of the new programming languages are R, Python, Haskell, Swift, C++, Java, Javascript and PHP.

However, you should know that in general sense there are three types of programming languages.

R is a pure object-oriented programming language being used for scientific purposes, and now it is being used extensively for machine learning as well.

Python is also a pure object-oriented programming language, and it is being used for mainly machine learning. However, you need to keep in mind that it supports the functional programming paradigm as well.

Haskell is a functional programming language and is the best in the functional paradigm as well. You can compare it with LISP, FORTRAN and PASCAL or COBOL, and you will find that Haskell is the best.

Swift is a pure object-oriented programming language, And by pure it means it never cheats anybody like if it says a variable is an int, it will be an int and not like C# here a string data type can be an integer data type. And this is not the correct thing. However, if you study in deep, you will find it is a necessary evil.

C++ and Java are imperative programming languages.

The Javascript and PHP are the scripting languages that support the object-oriented programming concepts but not fully, and they too fall under the imperative programming language list.

Explanation:

The answer is self explanatory.
