'Unexpected end of script'

I asked a question but I quickly found an answer. Here's the code anyway:

//Prints in specific location
function print(message){
  var outputDiv = document.getElementById('output');
  outputDiv.innerHTML = message;
}
//Builds a list from an array
function buildList(results){
  var listHTML = '<ol>';
   for (var i=0; i<results.length; i+=1){
     listHTML += '<li>' + results[i] + '</li>';}
  listHTML += '</ol>';
  return listHTML;
}

//Variables for quiz here
var questions = [
  ["What's my first name?","Danilo"],
  ["What's my middle name?","Armand"],
  ["What's my last name?", "Rodriguez"]
]
 var questionsGood = [];
 var questionsBad = [];
 var correctAnswers = 0;
 var wrongAnswers = 0;
 var asked;
 var answered;
 var goodAnswer;

//Asks array questions and keeps track of how many and which questions are right and wrong
for (var i = 0; i < questions.length; i +=1){
  var asked = questions[i][0];
  var goodAnswer = questions[i][1];
  var answered = prompt(asked);
    if (answered === goodAnswer){
    correctAnswers += 1;
      questionsGood.push(asked);
    } else {wrongAnswers +=1; questionsBad.push(asked)}
}
//If some questions are correct and some wrong this message displays
if (correctAnswers >= 1 && wrongAnswers >= 1){
var closeMessage = 'You got ' + '<strong>'+ correctAnswers +'</strong>'+ ' right and ' +'<strong>'+ wrongAnswers +'</strong>'+ ' wrong.'
closeMessage += '<h2> The questions you answered ' + '<strong>' + 'correctly' + '</strong>' + ' are: </h2>';
closeMessage += buildList(questionsGood);
closeMessage += '<h2> The questions you answered ' + '<strong>' + 'wrong' + '</strong>' + ' are: </h2>';
closeMessage += buildList(questionsBad);
print(closeMessage);}
//If all questions are correct this message displays
else if (wrongAnswers === 0){
  var allRight = '<strong>Congratulations! You answered all questions correctly!!!</strong>';
  print(allRight);}
//If all questions are wrong this message displays
else {
  var allWrong = 'bruh. ' + 'You got ' + '<strong>ALL</strong>' + ' the questions wrong.'
  print(allWrong);}

It was because I tried to test my code after adding an 'If' and 'else if' without a finishing 'else'

Actually, a final "else" following an "if/else...if" chain is optional.

I did not see the original code, but I might guess that the issue may have been mismatched braces.
