The if-else block occupies fewer lines, but the switch statements appear easier to read. Which option is superior, if any, from a technical standpoint?
Also, can anyone nitpick my code? 
// Choose a random number from 0-7
const randomNumber = Math.floor(Math.random() * 8);
// Prepare to store 8-Ball message
let eightBall;
// Pick from available 8-Ball messages:
// switch statements
switch(randomNumber) {
case 0:
eightBall = 'it is certain';
break;
case 1:
eightBall = 'it is decidedly so';
break;
case 2:
eightBall = 'reply hazy, try again';
break;
case 3:
eightBall = 'cannot predict now';
break;
case 4:
eightBall = 'do not count on it';
break;
case 5:
eightBall = 'my sources say no';
break;
case 6:
eightBall = 'outlook not so good';
break;
case 7:
eightBall = 'signs point to yes';
break;
}
// if-else statements
/* if (randomNumber === 0) {
eightBall = 'it is certain';

// Output 8-Ball message in all caps
console.log(`The Magic 8-Ball says:\n${eightBall.toUpperCase()}.`);
