line 6 document.write issues

Hello to whoever is reading this!

Below is my code. Lines 1-5 all work as I tested each part separately, but for some reason, my final document.write on line 6 will only write the string " ' + randomNumber + ' ". The document.write picks up on everything else properly, but not that particular part. I've been at this for awhile now, so my eyes are probably missing something very simple. Any help is greatly appreciated!

var randomNumber = Math.floor(Math.random() * 6) + 1;
var guess = prompt("I am thinking of a number between 1 and 6. What is it?");
if (parseInt(guess) === randomNumber) {
  document.write("<p>You are right!</p>");
} else {
  document.write("<p>WRONG! The correct number was ' + randomNumber + ' </p>");
}

Hi Blake,

Careful with your quotation marks! If you're opening with doubles, you have to close with doubles and vice-versa:

var randomNumber = Math.floor(Math.random() * 6) + 1;
var guess = prompt("I am thinking of a number between 1 and 6. What is it?");
if (parseInt(guess) === randomNumber) {
  document.write("<p>You are right!</p>");
} else {
  document.write("<p>WRONG! The correct number was " + randomNumber + " </p>");
}

Ahhhhh! I was under the impression that if I started with double and I intended to use another set of quotes following I would need to use the alternate, the single. Thank you for correcting my mistake!

Sure thing! There are times when you'd want to use both. For example, if you were outputting html with quotes in it, you'd want to do something like this:

document.write('<p class="red-text">WRONG! The correct number was ' + randomNumber + '</p>');
