what if we do it like this?

i was wondering if this would be a good practice since it seems to get the same results.

function getRandomNumber(upper, lower) {

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

}

getRandomNumber(6, 1);

any help will be appreciate.. thanks

That works just fine in this particular situation, but only because "lower" is being set to 1.

To make the formula more generic, it needs to compute the range with the method shown in the video.
