What is The Difference Between Smalltalk And Leda, Programming Languages

Smalltalk is a Compiled Programming Language, while Leda is a Logic-based Programming Language

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)

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)

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

Let us now look at the difference between the two:

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.

What is Leda Programming Language – A brief synopsis

This computer programming language is a blend of logic-based, functional, imperative and object-oriented programming. It is thus one of the multi-paradigm languages.
