How is the object model used in Smalltalk?
The Smalltalk object model Smalltalk’s programming model is simple and uniform: everything is an object, and objects communicate only by sending each other messages. However, this simplicity and uniformity can be a source of difficulty for programmers used to other languages.
What makes Smalltalk different from other programming languages?
Smalltalk is a “pure” object-oriented programming language, meaning that, unlike C++ and Java, there is no difference between values which are objects and values which are primitive types.
Is it hard to write Smalltalk in C?
Writing the performance critical part of the code in C but the rest in Smalltalk is typically quite difficult. Foreign function interfaces typically impose a high cognitive load on the programmer, as well as a run-time cost.
How are instance variables accessed in Smalltalk class?
Instance variables can be accessed by name in any of the instance methods of the class that defines them, and also in the methods defined in its subclasses. This means that Smalltalk instance variables are similar to protected variables in C++ and Java.
