* Returns a plain object with calendar information for a single valid locale
* (callers must perform this validation). The object will have these
* properties:
* firstDayOfWeek
* an integer in the range 1=Monday to 7=Sunday indicating the day
* considered the first day of the week in calendars, e.g. 7 for en-US,
* 1 for en-GB, 7 for bn-IN
* minDays
* an integer in the range of 1 to 7 indicating the minimum number
* of days required in the first week of the year, e.g. 1 for en-US,
* 4 for de
* weekend
* an array with values in the range 1=Monday to 7=Sunday indicating the
* days of the week considered as part of the weekend, e.g. [6, 7] for en-US
* and en-GB, [7] for bn-IN (note that "weekend" is *not* necessarily two
* days)
* NOTE: "calendar" and "locale" properties are *not* added to the object.

* Compares a BCP 47 language tag against the locales in availableLocales and
* returns the best available match -- or |undefined| if no match was found.
* Uses the fallback mechanism of RFC 4647, section 3.4.
* The set of available locales consulted doesn't necessarily include the
* default locale or any generalized forms of it (e.g. "de" is a more-general
* form of "de-CH"). If you want to be sure to consider the default local and
* its generalized forms (you usually will), pass the default locale as the
* value of |defaultOrNull|; otherwise pass null.
* Spec: ECMAScript Internationalization API Specification, 9.2.2.
* Spec: RFC 4647, section 3.4.
* Usage: result = intl_BestAvailableLocale("Collator", locale, defaultOrNull)
[[nodiscard]] extern bool intl_BestAvailableLocale(JSContext* cx, unsigned argc,

* Return the supported locale for the input locale if ICU supports that locale
* (perhaps via fallback, e.g. supporting "de-CH" through "de" support implied
* by a "de-DE" locale). Otherwise uses the last-ditch locale.
* Usage: result = intl_supportedLocaleOrFallback(locale)
[[nodiscard]] extern bool intl_supportedLocaleOrFallback(JSContext* cx,
unsigned argc,
JS::Value* vp);
* Returns the list of supported values for the given key. Throws a RangeError
* if the key isn't one of {"calendar", "collation", "currency",
* "numberingSystem", "timeZone", "unit"}.
* Usage: list = intl_SupportedValuesOf(key)
