Primitive data consists of simple characters or keywords, such as the numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9, or the strings "a", "b", and "c". As shown in Chapter 3, the primitive datatypes supported by ActionScript are number, string, boolean, undefined, and null. In this chapter, we'll explore how to define, examine, and change data of each type.
