Thus far you have learned that if statements allow you to evaluate a condition and run a block of code (Based on whether a condition evaluates to true or false). In addition, you have learned that you can provide alternate blocks of code by using else statements and, if you read carefully, you can also evaluate multiple conditions by using elseif statements.

Still, even with elseif statements, your code can get rather cumbersome when evaluating many conditions. In those cases, consider using the switch statement. Use switch statements when you have many conditions to check or when conditions evaluate to non true/false values.
