Okay, we’ve done a lot work covering logical operators. It’s time to put your knowledge to the test. In this episode, we have two challenges. We’ll start with the first one. First, I want you to define two variables. One should be called a constant myAge and set it to you age. The other should be a final called message that you’ll print out to the console.

const myAge = 47;
String message;

if (myAge >= 13 && myAge <= 18) {
    message = 'You are a teenager';
} else {
    message = 'You are not a teenager';
}

print(message);

const anotherMessage =

const anotherMessage = (myAge >= 13 && myAge <= 18)

const anotherMessage = (myAge >= 13 && myAge <= 18) ? 'You are a teenager'

const anotherMessage = (myAge >= 13 && myAge <= 18) ? 'You are a teenager' : 'You are not a teenager';

print(anotherMessage);
