Setup

const a = [...new Array(10000)].fill().map((_, i) => i)
const b = [...new Array(10000)].fill().map((_, i) => i)

const idListsMatch = (one, two) =>
  one.length === two.length && one.every(id => two.includes(id))
  
const idListsMatch2 = (one, two) => {
  if (one.length !== two.length) {
    return false
  }
  const lookup = new Set(one)
  return two.every(id => lookup.has(id))
}
