  // if iLoveJavaScript AND iLoveLearning:
  console.log("Awesome! Let's keep learning!");
} else if(!(iLoveJavaScript || iLoveLearning)) {
  // if NOT iLoveJavaScript OR iLoveLearning:
  console.log("Let's see if we can change your mind.");
} else {
  console.log("You only like one but not the other? We'll work on it.");
}
