Is it necessary to 'use strict' in articles.js?

After reading about use strict mode, I came across this on the MDN docs:

ECMAScript 2015 introduced JavaScript modules and therefore a 3rd way to enter strict mode. The entire contents of JavaScript modules are automatically in strict mode, with no statement needed to initiate it.

Since article.js is a module, is it unnecessary to use strict?

It certainly sounds like you wouldn't ever use that in a module. Why not try a little experiment ... see if something like an implicit global causes an error. Then edit or add a comment to this question to let us know!
