What is The Difference Between OPAL And Self, Programming Languages

OPAL is an Interpreted Programming Language, while Self is an Object-Oriented Programming Language

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)

What are Object-Oriented Programming Languages

Object-oriented programming (OOP) is a programming paradigm based on the concept of “objects”, which may contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods. In OOP, computer programs are designed by making them out of objects that interact with one another. (Wikipedia)

While OPAL is an Interpreted Programming Language, and Self is an Object-Oriented Programming Language

Let us now look at the difference between the two:

What is OPAL Programming Language – A brief synopsis

The name stands for Optimized Applicative Language and is a functional programming language developed at the Technical University of Berlin.

What is Self Programming Language – A brief synopsis

It is an object-oriented prototype-based computer programming language. NewtonScript is used to write programs for Apple Newton and is largely influenced by Self.
