switch (screen.orientation.type) {
case "landscape-primary":
console.log("That looks good.");
break;
case "landscape-secondary":
console.log("Mmm… the screen is upside down!");
break;
case "portrait-secondary":
case "portrait-primary":
console.log("Mmm… you should rotate your device to landscape");
break;
default:
console.log("The orientation API isn't supported in this browser :(");
}
