JavaScript : Object-Oriented Programming

Summary

In this chapter, you learned a lot about the basic building blocks of a JavaScript program. Now you know the primitive data types:

• Number
• String
• Boolean
• Undefined
• Null

You also know quite a few operators:

• Arithmetic operators: +, -, *, /, and %
• Increment operators: ++ and --
