Code works most of the time, others I get an odd Console error.

Hi there. For the most part my code (below) is working. Other times, I am seeing: "Uncaught TypeError: Cannot read property 'impl' of undefined(anonymous function) @ extensions::messaging:184".

I have seen this on some other workspaces, normally when I have an error. Any ideas?

var correctAnswers = 0;
function print(message) {
  document.write(message);
}
var qAndA = [
  ["What is the capitol of Oregon?", "Salem"],
  ["What city in Oregon has the highest population?", "Portland"],
  ["What city was this quiz created in?", "Newberg"]
];
for(i=0; i<qAndA.length; i+=1){
  if (prompt(qAndA[i][0])===  qAndA[i][1]){
    correctAnswers += 1;
  }
}
print("You got " + correctAnswers + " questions right!");

I think this error doesn't come from your code but from a browser extension.

Could you try to execute your code in a clean browser or incognito window?
