slice that ignores array boundaries

const slice = (array, from, to) => {
  let realFrom = from < 0 ? array.length + from : from
  let realTo = to > array.length ? to - array.length : to
  return (realFrom <= realTo
    ? array.slice(realFrom, realTo)
    : array.slice(realFrom, array.length).concat(array.slice(0, realTo))
  )
}
