> [!NOTE]
> You may want new Intl.DateTimeFormat().resolvedOptions().locale instead. This package is useful for CLI tools as it also reads locale from environment variables (LC_ALL, LC_MESSAGES, LANG, LANGUAGE), which the Intl API does not fully support (it only respects LC_ALL).
Useful for localizing your module or app.
POSIX systems: The returned locale refers to the LC_MESSAGES category, suitable for selecting the language used in the user interface for message translation.
``sh`
npm install os-locale
`js
