## Description

/**
 * Formats the user's language and country code based on the browser's language settings.
 *
 * @returns {string} A formatted language code in the form of `language-country` (e.g., `en-US`).
 *
 * ### Functionality:
 * - Retrieves the user's browser language using `navigator.language`.
 * - Splits the language string into a language code (e.g., `en`) and a country code (e.g., `US`).
 * - Checks if the country code is valid (i.e., not numeric):
 *   - If valid, returns the original `language-country` format.
 *   - If invalid or missing, assigns a default country code based on the language.
 * - Returns the final formatted language string.
