1. Let key be ? ToString(key).

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.
