Roll one item from a pool using linear search. Simple and great for one-time use pools. Use GachaMachine if you will be picking multiple items from the same pool.

const items = [
  { result: "SSR cool character", chance: 1 },
  { result: "Kinda rare character", chance: 3 },
  { result: "Mob character", chance: 5 },
  { result: "Mob character", chance: 5 },
  { result: "Mob character", chance: 5 },
]
roll(items) // Rolls one item from the list of items

const items = [
  { result: "SSR cool character", chance: 1 },
  { result: "Kinda rare character", chance: 3 },
  { result: "Mob character", chance: 5 },
  { result: "Mob character", chance: 5 },
  { result: "Mob character", chance: 5 },
]
roll(items, 19) // Rolls one item from the list of items, faster because the total chance is known.
