TL;DR - Mobify.js fires off one request to Jazzcat, which grabs all of your scripts and returns back a single concatenated file. As for how it actually works, we use the DOM pre-parsing capabilities of Mobify.js to grab script URLs and remove the scripts from the source document before it's rendered by the browser. THEN a request is made for the single javascript file from Jazzcat.
