Documentation: getLocaleLang Function in intlayer
Description
The getLocaleLang function extracts the language code from a locale string. It supports locales with or without country codes. If no locale is provided, it defaults to returning an empty string.
Parameters
locale?: Locales
- Description: The locale string (e.g., Locales.ENGLISH_UNITED_STATES, Locales.FRENCH_CANADA) from which the language code is extracted.
- Type: Locales (optional)
Returns
- Type: string
- Description: The language code extracted from the locale. If the locale is not provided, it returns an empty string ('').
Example Usage
Extracting Language Codes:
import { getLocaleLang, Locales } from "intlayer";getLocaleLang(Locales.ENGLISH_UNITED_STATES); // Output: "en"getLocaleLang(Locales.ENGLISH); // Output: "en"getLocaleLang(Locales.FRENCH_CANADA); // Output: "fr"getLocaleLang(Locales.FRENCH); // Output: "fr"Edge Cases
No Locale Provided:
- The function returns an empty string when locale is undefined.
Malformed Locale Strings:
- If the locale does not follow the language-country format (e.g., Locales.ENGLISH-US), the function safely returns the part before '-' or the entire string if no '-' is present.
