  @param {Object} iterable the iterable object to be turned into a true Array.
  @param {Number} start (Optional) a zero-based index that specifies the start of extraction. Defaults to 0
  @param {Number} end (Optional) a 1-based index that specifies the end of extraction. Defaults to the last
  index of the iterable value
  @return {Array} array
