I don't understand why this doesn't work. If you call functions in the same way then it should work.
var upper = 10;
var randomNumber = getRandomNumber(upper);
var guess;
var attempts = 0;
const getRandomNumber = upper => Math.floor(Math.random() * upper) + 1;
while (guess !== randomNumber){
guess = getRandomNumber(upper);
attempts += 1;
}
document.write(getRandomNumber(upper));
document.write("The number was " + randomNumber + "<br />");
document.write(" It took the computer " + attempts + " attempts");

But what's causing the trouble here is that an assignment is not hoisted like a conventional function definition would be. So the assignment of "getRandomNumber" needs to be done before you call it to create "randomNumber".
