Weighted Random Picker

Generates option-picker functions from relative probabilities:

// When relative probabilities are not provided, it gives equal weight to each option
const CoinFlip = RandomPicker(["Heads", "Tails"])
 
print(CoinFlip()) // "Heads"
print(CoinFlip()) // "Tails"
 
const DiceRoll = RandomPicker([1, 2, 3, 4, 5, 6])
 
const CoinFlipOrDiceRoll = RandomPicker(
    // calls CoinFlip over DiceRoll at a 3:1 ratio
    // in other words, CoinFlip gets set to 0.75, DiceRoll becomes 0.25
    [CoinFlip, DiceRoll],
    [       3,        1]
)
 
CoinFlipOrDiceRoll()() // 1
CoinFlipOrDiceRoll()() // Heads
CoinFlipOrDiceRoll()() // 5
