// Make a keyless car EVEN BETTER!
// We are improving our car from previous exercise now.
// Solutions to future exercises will be in the .js file (meaning Javascript file) from now on.
var age = prompt("What is your age?");
if (Number(age) < 18) {
alert("Sorry, you are too yound to drive this car. Powering off");
} else if (Number(age) > 18) {
alert("Powering On. Enjoy the ride!");
} else if (Number(age) === 18) {
alert("Congratulations on your first year of driving. Enjoy the ride!");
}
//1. Make the above code have a function called checkDriverAge(). Whenever you call this function, you will get prompted for age. Use Function Declaration to create this function.
// Notice the benefit in having checkDriverAge() instead of copying and pasting the function everytime?
//2. Create another function that does the same thing, called checkDriverAge2() using Function Expression.
//BONUS: Instead of using the prompt. Now, only use console.log and make the checkDriverAge() function accept an argument of age, so that if you enter:
checkDriverAge(92);
it returns "Powering On. Enjoy the ride!".

return "Powering On. Enjoy the ride!";
} else if (Number(age) === 18) {
return "Congratulations on your first year of driving. Enjoy the ride!";
