Math floor to include the last number
what is the different between the two codes or which one should I use to include number 6 Math.floor(Math.round() * 6) + 1; and Math.floor(Math.round() * 7)

The first one (where you multiply by 6 and add 1) will give you a number from 1 to 6.
The second one (multiply by 7) will give you a number between 0 and 6.
Both include 6, and you didn't mention what this might be used for; but if you're trying to emulate rolling dice, the first one would be the correct formula.
