What is The Difference Between Q And Janus, Programming Languages

Q is an Interpreted Programming Language, while Janus is a Logic-based Programming Language

What are Interpreted Programming Languages

An interpreted language is a programming language for which most of its implementations execute instructions directly, without previously compiling a program into machine-language instructions. The interpreter executes the program directly, translating each statement into a sequence of one or more subroutines already compiled into machine code. (Wikipedia)

What are Logic-based Programming Languages

Logic programming is a type of programming paradigm which is largely based on formal logic. Any program written in a logic programming language is a set of sentences in logical form, expressing facts and rules about some problem domain. (Wikipedia)

While Q is an Interpreted Programming Language, and Janus is a Logic-based Programming Language

Let us now look at the difference between the two:

What is Q Programming Language – A brief synopsis

It is called Q for being an equational programming language. It is an interpreted functional language that was designed by Albert Graf at the University of Mainz in Germany. It can be described as a set of equations used to evaluate expressions.
