Listing 16-11 the first part of the ternary conditional operator is the statement a ==5, which is using the equality comparison operator to test to see whether a is equal to 5.
the next part of Listing 16-1, you have two possible actions that can take place separated by the semicolon (ะ). The first action, “We’re good,” takes place if the statement is true, while the second action, “Oops, not quite,” takes place if the statement is not true.
The ternary conditional operator is a shorthand version of the if statement that is covered in more detail in Chapter 23.
