What is The Difference Between Haskell And OPAL, Programming Languages

Both Haskell and OPAL 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 Haskell and, are both Interpreted Programming Languages

Let us now look at the difference between the two:

What is Haskell Programming Language – A brief synopsis

Named in honor of Haskell Curry, a logician, Haskell is a standardized purely functional language. It supports pattern matching, definable operators, single assignment, algebraic data types and recursive functions.
