Explain this word ( Upper ) in this function please.

Function getRadomNumber( upper ) { var randomNumber = Math.floor( Math.random() * upper ) + 1; return randomNumber; } console.log( getRandomNumber(6) );

In the video, I have no clue where this "upper" word came from, what it does and how it relates to the function. Can someone explain this to me?

Hello!

upper is the parameter you give to the function to determine the range the random number is picked from.

For example getRandomNumber(6) will return a random number between 0 and 6, getRandomNumber(10) will return a random number between 0 and 10 and so on.

Hope it helped!
