What is The Difference Between Janus And Self, Programming Languages

Janus is a Logic-based Programming Language, while Self is an Object-Oriented 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 Object-Oriented Programming Languages

Object-oriented programming (OOP) is a programming paradigm based on the concept of “objects”, which may contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods. In OOP, computer programs are designed by making them out of objects that interact with one another. (Wikipedia)

While Janus is a Logic-based Programming Language, and Self is an Object-Oriented 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 Self Programming Language – A brief synopsis

It is an object-oriented prototype-based computer programming language. NewtonScript is used to write programs for Apple Newton and is largely influenced by Self.
