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);
``````
