What is The Difference Between Janus And J, Programming Languages

Janus is a Logic-based Programming Language, while J 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)

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 J Programming Language – A brief synopsis

Ken Iverson and Roger Hui developed this programming language that requires only the basic ASCII character set. It is an array programming language that works well with mathematical and statistical operations.
