  1. Let key be ? ToString(key).

  5. Else if key is "numberingSystem", then

  9. Return ! CreateArrayFromList( list ).

  AvailableNumberingSystems ( )
    The AvailableNumberingSystems abstract operation returns a List, ordered as
    if an Array of the same values had been sorted using %Array.prototype.sort%
    using undefined as comparefn, that contains unique numbering systems
    identifiers identifying the numbering systems for which the implementation
    provides the functionality of Intl.DateTimeFormat, Intl.NumberFormat, and
    Intl.RelativeTimeFormat objects. The list must include the Numbering System
    value of every row of Table 4, except the header row.
