If Statements

• An if statement identifies which code block (scope) to run based on the value of a Boolean expression 

  • A Boolean expression must evaluate to either a True or False value 

  • If the condition (the Boolean expression) is True, then the scope immediately following the if statement is executed

  • If the condition is False, and there is an else clause, then the scope immediately following the else statement is executed
