What is The Difference Between Clean And Spin, Programming Languages

Both Clean and Spin are Interpreted Programming Languages
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)
Since Clean and, are both Interpreted Programming Languages
Let us now look at the difference between the two:
What is Clean Programming Language – A brief synopsis
It is a purely functional programming language that supports portability across platforms, automatic garbage collection, multiple data structures and referential transparency, which means that a function with a given input will always give the same output.
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.
