What is The Difference Between Janus And Spin, Programming Languages

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

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)

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)

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

Let us now look at the difference between the two:

What is Janus Programming Language – A brief synopsis

Janus supports concurrent and constraint programming.

What is Spin Programming Language – A brief synopsis

It is a multitasking object-oriented programming language whose compiler converts the Spin code into bytecodes. Multiple Spin code threads can run at a time, thus enabling multitasking. Spin was developed by Chip Gracey of Parallax.
