Also the classes and metaclasses are treated as objects. There are two types of variables used in Smalltalk. These are instance variables and temporary variables and are declared within enclosed vertical bars at the top of the method name. Applications and Uses Smalltalk has influenced many other programming languages like C, Python, Ruby, Java and has an effective computational power. This is the main reason that it is widely used in web applications, Internet of Things(IoT), medical fields, artificial intelligence, machine learning, mobiles, desktops and in many other industrial fields. Its a versatile language and provides an interactive graphical platform and thus many web developing companies are using Smalltalk on a very large scale.
