Documentation: getLocaleName Function in intlayer

Description

The getLocaleName function returns the localized name of a given locale (targetLocale) in the display locale (displayLocale). If no targetLocale is provided, it returns the name of the displayLocale in its own language.

Parameters

• displayLocale: Locales

  • Description: The locale in which the name of the target locale will be displayed.
  • Type: Enum or string representing valid locales.

• targetLocale?: Locales

  • Description: The locale whose name is to be localized.
  • Type: Optional. Enum or string representing valid locales.

Returns

• Type: string
• Description: The localized name of the targetLocale in the displayLocale, or the displayLocale's own name if targetLocale is not provided. If no translation is found, it returns "Unknown locale".

Edge Cases

• No targetLocale provided:
  • The function defaults to returning the displayLocale's own name.
• Missing translations:
  • If localeNameTranslations does not contain an entry for the targetLocale or the specific displayLocale, the function falls back to the ownLocalesName or returns "Unknown locale".
