Windows Locale is a JavaScript module that provides access to Windows Language Code Identifier (LCID) information, allowing developers to retrieve details like language name, location, ID, and locale tag for various Windows locales. It's designed for JavaScript developers working on projects that require locale-specific functionality in Windows environments, such as internationalization or localization tasks. The module is easy to install via npm or yarn and contains no dependencies, making it a lightweight solution for handling Windows locale data.
