In most of the JavaScript programs, which we learned so far, the lines of code were executed in the same order in which they appeared in the program. Each code was executed only once. Thus, the code did not include tests to determine if the conditions were true or false or we did not perform any logical statements.
In this chapter, you are going to learn some logical programming. You will learn about the following topics:
Loops
If statement
Switch case
You already know how to embed JavaScript codes on an HTML document. Before starting this chapter, you will learn a few HTML tags and JavaScript methods. These methods and tags will be used throughout the book.
