3. The open source programming
language of Squeak is radically object-oriented
The programming language is the
Squeak Language, which is
Smalltalk +
Morphic.
In many ways, Smalltalk is the mother of object-oriented programming languages,
and indeed it is a direct precursor and the inspiration of the Apple and Windows
interface. Yet the Squeak approach to object-oriented programming is quite
different from - say - Delphi or Java or C# or Visual Basic, all of which also
are nominally "object-oriented". In fact, these other "object-oriented"
programming languages have taken over some techniques and ideas that started
(mostly) in Smalltalk - but they do NOT immerse the uses in a total computing
environment made from objects, in which the user has the full open source code
of all the objects in the environment, and can directly access and change the
code of any object that is working in the system, that is itself entirely
composed from objects programmable inside the system.
