What is The Difference Between Janus And PL/I, Programming Languages

Janus is a Logic-based Programming Language, while PL/I is a Procedural 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 Procedural Programming Languages

Procedural (imperative) programming implies specifying the steps that the programs should take to reach to an intended state. A procedure is a group of statements that can be referenced through a procedure call. Procedures help in the reuse of code. Procedural programming makes the programs structured and easily traceable for program flow.

While Janus is a Logic-based Programming Language, and PL/I is a Procedural 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 PL/I Programming Language – A brief synopsis

It is an imperative computer programming language targeted at scientific and engineering applications. Mainly intended to perform data processing, it also supports structured programming and recursion.
