why did he create a new variable inside of the loop called randNum when he already created a function to do that?

i'm assuming he just wanted to give the function a different name inside of the loop? i'm not sure just trying to figure out logically why he did that?

randNum is used to store the value of the random number when it is generated.

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

This function is used to generate a random number from 1 to upper.

var randNum = randomNumber(6);

This is used to call the function randomNumber and store the random number returned inside the variable randNum to be used however it needs to be.
