normalizes weird cross browser issues and tries to return the users selected language in 100% client side JS by looking at various properties on the
note that another technique used to detect the browsers user-set language preference is to look at the
accept-language header set on outgoing http requests, but this requires making a round trip XHR to a server, which is what jquery-browser-language does.
however, it seems that as of 2014 you can get the user specified language without making a HTTP request (see
index.js for details)
npm install browser-locale
var locale =// locale will be e.g. en-US or undefined if it could not be detected (e.g. you are in a super weird browser)
Not all browsers are consistent in their capitalization of language tags,
en-us. Keep this in mind when looking for matches in locale
