What is The Difference Between Janus And Limbo, Programming Languages

Janus is a Logic-based Programming Language, while Limbo is a Concurrent 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 Concurrent Programming Languages

Concurrent programming is a computer programming technique that provides for the execution of operations concurrently â€” either within a single computer, or across a number of systems. In the latter case, the term distributed computing is used. (Wikipedia)

While Janus is a Logic-based Programming Language, and Limbo is a Concurrent 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 Limbo Programming Language – A brief synopsis

Developed at the Bell Labs, Limbo is used for programming distributed systems. Its striking feature is its compiler’s ability to generate architecture-independent object code. Limbo is used for applications running on Inferno operating system. Alex that was initially a part of the Plan 9 operating system is the predecessor of Limbo.
