Langs

`$ npm install langs`

This library provides ISO 639-1/2/3 language codes with English and local names. It can be installed in whichever way you prefer, but I recommend NPM.

What's with all the ISO version numbers?

ISO 639 is broken up into many different parts, each either defining language codes or defining standards for codes in later versions. The ones included in this library are:

ISO 639-1 2 characters, one per language or ISO 639 macrolanguage
ISO 639-2/2T 3 characters, one per language
ISO 639-2B 3 characters, mostly the same as 639-2T but with some derived from their English name rather than local name
ISO 639-3 3 characters, mostly the same as 639-2T but using the canonical ISO 639 macrolanguage code

The macrolanguages described above cover cases where a language is considered to be a dialect of another in some standards but not in others, e.g Standard Arabic arb and Arabic ara. There's more information on the Wikipedia page.
