goog.i18n.LocaleFeature

The locales natively supported in ListFormat by all modern browsers.

ECMASCRIPT_COMMON_LOCALES A set of locales supported by all modern browsers in ECMASCRIPT Intl. Common across all of the modern browsers and Android implementations available in 2019 and later.

ECMASCRIPT_INTL_OPT_OUT A global flag that an application can set to avoid using native ECMAScript Intl implementation in any browser or Android implementations. This may be necessary for applications that cannot use the regular setting of goog.LOCALE or that must provide the Javascript data and to create formatted output exactly the same on both client and server.

Default value is false. Applications can set this to true so compilation will opt out of the native mode.

ECMASCRIPT_LISTFORMAT_COMMON_LOCALES_2022 is true if goog.LOCALE is one of the locales below that are supported by modern browsers (Chrome, Firefox, Edge, Safari) as of January 2022.
