WHY MY LOOP RUNS ENDLESSLY?

A QUESTION ABOUT THIS VIDEO.

I have the same code and I followed the video correctly but the loop runs endlessly. Help!

Here's my complete code:

var randomNumber = getRandomNumber(10);
var guess;
var guessCount = 0;
var correcGuess= false;

function getRandomNumber( upper ) {
  var num = Math.floor(Math.random() * upper) + 1; 
  return num;
}

do {
guess = prompt("I am thingking of a number between 1 and 10. What is it?");
guessCount +=1;
  if(parseInt(guess) === randomNumber) {
    correctGuess= true;
  }
} while ( correcGuess=false )
document.write('<h1> You guessed the number! </h1>');
document.write('It took you ' + guessCount + ' times to guess the correct number.');

SORRY! HERE'S THE CODE THAT I COPIED FROM THE VIDEO:

var randomNumber = getRandomNumber(10);
var guess;
var guessCount = 0;
var correcGuess= false;

function getRandomNumber( upper ) {
  var num = Math.floor(Math.random() * upper) + 1; 
  return num;
}

do {
guess = prompt("I am thingking of a number between 1 and 10. What is it?");
guessCount +=1;
  if(parseInt(guess) === randomNumber) {
    correctGuess= true;
  }
} while ( ! correctGuess)
document.write('<h1> You guessed the number! </h1>');
document.write('It took you ' + guessCount + ' times to guess the correct number.');

You just spelled correctGuess wrong when you created it on line 4. Replace correcGuess with correctGuess and it will work fine!

You can always try looking in the javascript console, that was how i found the bug. : )
