    6                     Conditional Statements

                                                                  in JavaScript

                          Let’s surf
                               Conditional Statements

                       Let’s PLug-in

                         If a = 8, b = 2 and c = 20, then what will be the output of the following statements:
                         1.   document.write(a > b && b < c)      =    ____________________
                         2.   document.write (a * b + c)          =    ____________________
                         3.   document.write (a/b + c)            =    ____________________
                         4.   document.write (a > b || b > c)     =    ____________________

                         5.   document.write (a * b - 2 + c)      =    ____________________

                      There are situations in life when we need to decide something based on a situation. For example, if it
                      rains, I will stay at home or else I shall visit the market. Similar situations arise in programming as well,
                      where we need to make some decisions and based on these decisions, execute a set of commands.
                      We need to determine which action is to be taken and which statement is to be executed, if the
                      outcome is true or false. In this chapter, we will learn about conditional statements of JavaScript.

                             CONDITIONAL STATEMENTS

                      Decision making in JavaScript is done by called conditional statements which decide the flow of
                      program execution. The following conditional statements are available in JavaScript:
                      •   if statement

                      •   if...else statement

                      •   Nested if statement
                      •   Switch statement
