--description--
An else statement can be conditional with an else if statement. At the end of the if statement, add an else if statement to check if monsterHealth is less than or equal to zero. Inside the else if block, call the defeatMonster() function.
Here is an example of an if statement with else if and else:
if (num > 15) {
return "Bigger than 15";
} else if (num < 5) {
return "Smaller than 5";
} else {
return "Between 5 and 15";
}
--hints--
See description above for instructions.
