If you want a name of an arbitrary language in an arbitrary language (e.g, how to say "Korean language" in Japanese), you can use Unicode CLDR data.

# => 'inglese'

But not sure if the package only supports Node.js or also supports browsers. If not, you may search for other libraries or write your own code to parse CLDR directly.
