Return the value right away?

I wonder if there's any difference between storing the value in a const and then returning the const vs returning the value right away.

function getRandomNumber() { const randomNumber = Math.floor( Math.random() * 6 + 1 ) return randomNumber }

vs.

function getRandomNumber() { return Math.floor( Math.random() * 6 + 1 ) }

*EDIT: Fixed an error in the 2nd example, as suggested by Robert.

Hi Steve, they're basically doing the same thing either way. The one with the variable perhaps has greater readability. But both create and return a random number. And actually, a small adjustment should be made to your second example. Since you're not declaring the randomNumber variable, you would to include that in that second example. Should be like this:

function getRandomNumber() { return Math.floor( Math.random() * 6 + 1 ) }

Hope that helps. :thumbsup:

Hi Robert,

Thanks, that makes sense :)
