What are the changes presented by ActionScript?

- ActionScript removed the differences between the primitive and reference types that are made in the object oriented languages.

- ActionScript considers all variables as references types and provide way to inherit the features easily.

- Objects belong to the primitive data types of the ActionScript and use the special operators to pass the value.

- Variables are of primitive type and the data types are used as a parameter to be passed to a function.

- The variables can be used inside the function without altering the original values used in other functions.
