Why does my code crash if I do this way?

var  count  =  0;

function getRandomNumber( upper ){
  var upper = 100;
  return   Math.floor( Math.random() * upper ) + 1 ;
}

while ( count !== getRandomNumber() ){
  count++;
}

console.log( getRandomNumber() );

console.log( count );

As count increases the range for guessing the correct random number decreases (between count and 100). Once count is greater than 100 you have an infinite loop.

Oh, I see. Thank you for making it clearer to me.
