Hello i have a question on why he has var = randomNumber = getRandomNumber(upper) as a variable with a function.
Also i would like to know what the purpose of this variable is.

Look again, there's only one "=" in that statement:
var randomNumber = getRandomNumber(upper);
This statement uses the "getRandomNumber" function to get a value to store into the new variable "randomNumber" that is created.
And the purpose of the variable is to store that random number so it can be compared to another one later to check for a match.
