Getting Started
ISO 639 is Internationally recognized code for the representation of more than 500 languages or language families.
About
ISO 639, Code for individual languages and language groups, can be applied across many types of organization and situations. It is needed for the basic settings of billions of user interfaces to ICT systems and devices, as well as for the indication of different language versions of websites. It is indispensable for information management in publishing, librarianship, and for large networks.
Using a language identifier (of two or three letters), rather than the name of a language, has many benefits as some cultures may have different names for the same language, while some languages may share the same, or similar, names even though they are unrelated.
Usage
If on the server side, you can use language code data as API response data.
If it is on the client, such as Web App, you can rely on CDN or npm package installation and import into the project.
