| // ScriptEd has a totally awesome nightclub. It's called FUNKTION. | |
| // Unfortunately we spent all our money on lights and speakers and cannot afford a bouncer. | |
| // Your job is to write a function to replace our bouncer with Javascript. | |
| // I wrote a function called yearsSinceDate to help you. (It's at the bottom of this code.) | |
| // Example usage: My cat's birthday is 4/9/2007. How old is she? | |
| var missyAge = yearsSinceDate(4, 9, 2007); | |
| console.log("Missy is " + missyAge + " years old"); | |
| // Missy is 9.87671698798199 years old | |
| // INSTRUCTIONS | |
| // Declare a function called bouncer that takes three parameters (for a birthday): month, day, year. | |
| // If we call bouncer with the birthday of a person 21 or over, it should console.log the words "Welcome to Funktion." | |
| // If we give bouncer the birthday of someone under 21, it should console.log the words "Sorry, not old enough" | |
| // HINT: remember the > and < operators for numbers! | |
| // HINT: you will need if and else statements | |
| // Start your code here! | |
| // !!!!! Starter Code!! Don't change anything below here !!!!! | |
| // Also, don't worry about how these work, but you can probably figure it out if you read it :) | |
