Having trouble getting the attempts variable to count. My browser says attempts are 0. ¯\_(ツ)_/¯

var upper = 10000;
var randomNumber = getRandomNumber(upper);
var guess;
var attempts = 0;

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

while( guess ==! randomNumber ) {
  guess = getRandomNumber( upper );
  attempts += 1;
}

document.write("<p>The random number was " + randomNumber + "</p>");
document.write("<p>It took the program " + attempts + " attemps to guess the random number.</p>");

U have given an invalid condition for your while loop there is nothing called ==! its !== this will fix it hopefully If this helped, rate my answer as best
