return Math.floor( Math.random() * upper ) + 1;

231,122 PointsOn line 4, the target "randomNumber" is set by calling "getRandomNumber". But since it it called without an argument, the formula will generate a result that is not a number ("NaN").
Since nothing matches "NaN", the loop condition will never be met and the loop will run continuously.
Just supply an argument when you call "getRandomNumber" (I assume you intended to use "upper") to fix the issue.
