`Math.random` returns a pseudo-random number between 0 and 1.
a pseudo-random number is generated by an algorithm, it is not
technically actually random, but for all intents and purposes
it is random enough that no human should be able to find a
pattern

// First Math.random give us a random number between 0 and 0,99999

// And we round dow with Math.floor
// We add 1 so the result will never be 0
