D&D Stat Roller

README.md

Rolling stats in D&D

1. Roll a 6 sided die 4 times.
2. Remove the lowest dice result.
3. Add up the remaining numbers to get an ability score.
4. Write down this ability score on note paper.
5. Repeat these steps until you have 6 ability scores.

  // roll 4 times and add the totals together
  for (let i=0; i < 4; i++){
    const roll = rollD6()
    sumOfRolls += roll
    smallestRoll = roll < smallestRoll ? roll : smallestRoll
  }

  // drop the smallest roll
  sumOfRolls -= smallestRoll
  return sumOfRolls
}

const getAllStats = () => {
  let allRolls = []

  // roll 6 stats
  for (let i=0; i<6; i++){
    allRolls[i] = getOneStat()
