The files in this directory are optimized for use with Node.js, hence the require('../moment') calls at the beginning of each file.
If you are looking to use these files in the browser, the minified version of these files in /min/lang/ are a better fit. We do some trickery to make each language file work with or without requirejs. If you are interested in the details, check out /tasks/minify-lang.js.
