get Intl.Locale.prototype.baseName
3. Return GetLocaleBaseName(_loc_.[[Locale]]).
GetLocaleBaseName
2. Return the longest prefix of _locale_ matched by the
<code>unicode_language_id</code> Unicode locale nonterminal.
get Intl.Locale.prototype.language
3. Return GetLocaleLanguage(_loc_.[[Locale]]).
GetLocaleLanguage
1. Let _baseName_ be GetLocaleBaseName(_locale_).
2. Assert: The first subtag of _baseName_ can be matched by the
<code>unicode_language_subtag</code> Unicode locale nonterminal.
3. Return the first subtag of _baseName_.
get Intl.Locale.prototype.script
3. Return GetLocaleScript(_loc_.[[Locale]]).
GetLocaleScript
1. Let _baseName_ be GetLocaleBaseName(_locale_).
2. Assert: _baseName_ contains at most one subtag that can be matched by the
<code>unicode_script_subtag</code> Unicode locale nonterminal.
3. If _baseName_ contains a subtag matched by the
<code>unicode_script_subtag</code> Unicode locale nonterminal, return
that subtag.
4. Return *undefined*.
get Intl.Locale.prototype.region
3. Return GetLocaleRegion(_loc_.[[Locale]]).
GetLocaleRegion
1. Let _baseName_ be GetLocaleBaseName(_locale_).
2. NOTE: A <code>unicode_region_subtag</code> subtag is only valid
immediately after an initial <code>unicode_language_subtag</code> subtag,
optionally with a single <code>unicode_script_subtag</code> subtag
between them. In that position, <code>unicode_region_subtag</code> cannot
be confused with any other valid subtag because all their productions are
disjoint.
3. Assert: The first subtag of _baseName_ can be matched by the
<code>unicode_language_subtag</code> Unicode locale nonterminal.
4. Let _baseNameTail_ be the suffix of _baseName_ following the first
subtag.
5. Assert: _baseNameTail_ contains at most one subtag that can be matched by
the <code>unicode_region_subtag</code> Unicode locale nonterminal.
6. If _baseNameTail_ contains a subtag matched by the
<code>unicode_region_subtag</code> Unicode locale nonterminal, return
that subtag.
7. Return *undefined*.
get Intl.Locale.prototype.variants
3. Return GetLocaleVariants(_loc_.[[Locale]]).
GetLocaleVariants
1. Let _baseName_ be GetLocaleBaseName(_locale_).
2. NOTE: Each subtag in _baseName_ that is preceded by *"-"* is either a
<code>unicode_script_subtag</code>, <code>unicode_region_subtag</code>,
or <code>unicode_variant_subtag</code>, but any substring matched by
<code>unicode_variant_subtag</code> is strictly longer than any prefix
thereof which could also be matched by one of the other productions.
3. Let _variants_ be the longest suffix of _baseName_ that starts with a
*"-"* followed by a <emu-not-ref>substring</emu-not-ref> that is matched
by the <code>unicode_variant_subtag</code> Unicode locale nonterminal. If
there is no such suffix, return *undefined*.
4. Return the substring of _variants_ from 1.
