const randomNumbers = Math.floor(Math.random() * 8);switch(randomNumbers){

switch(randomNumbers)
case 0:
eightBall = ‘It is certain’;

eightBall = 'It is decidedly so';

Hello @shahanjrp, welcome to the forums! Unfortunately we can’t just give away answers on the forum, but if you have a specific question about turning switch blocks into if…else blocks, we could answer that.

In general, when you turn a switch block into an if…else block, each case becomes its own else if condition, like so:

//this is the switch block I want to turn into an if…else if…else block:
let aNumber = 5;
switch (aNumber) {
case 1:
  console.log("1");
  break;
case 2:
  console.log("2!");
  break;
default:
  console.log("Not 1 or 2.");

//Here is the above code turned into an if…else if…else block:
if (aNumber == 1){//first case is turned into the if.
console.log("1");
}else if (aNumber == 2){//seconde case is turned into an else if.
console.log("2");
//Note all case statements after the first one get turned into else if blocks
}else{//the default 
console.log("Not 1 or 2.");
}

Generally, one would prefer to keep code as simple as possible, so you would generally not want to turn a switch block back into an if…else block.

I hope this helps!
