What is The Difference Between Prolog And Smalltalk, Programming Languages

Prolog is a Logic-based Programming Language, while Smalltalk is a Compiled 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 Compiled Programming Languages

A compiled language is a programming language whose implementations are typically compilers (translators that generate machine code from source code), and not interpreters (step-by-step executors of source code, where no pre-runtime translation takes place). (Wikipedia)

While Prolog is a Logic-based Programming Language, and Smalltalk is a Compiled Programming Language

Let us now look at the difference between the two:

What is Prolog Programming Language – A brief synopsis

It is a general-purpose programming language that supports logic programming and is often linked with artificial intelligence and computational linguistics. The language is declarative and the program logic is expressed in the form of relations. Mercury is a functional logic programming language that is based on Prolog. Strawberry Prolog is a dialect of Prolog, which is supposed to be easy to use. Visual Prolog is a strongly typed extension of Prolog that supports object-oriented programming. It is a compiled logic-based programming language.

What is Smalltalk Programming Language – A brief synopsis

It is a reflective, object-oriented programming language that supports dynamic typing. Alan Kay, Adele Goldberg, Dan Ingalls, Scott Wallace, Ted Kaehler and their associates at Xerox PARC developed Smalltalk. They designed it for educational use and it soon became popular. VisualWorks is a prominent implementation of Smalltalk. Squeak is a programming language that is in the form of an implementation of Smalltalk. Scratch is a visual programming language based on Squeak.
