A framework is usually the foundational code for an app, for sure. In this case it was a bona fide JavaScript framework, Ext JS.

It is that big because it implements a lot of things that other frameworks don't even try to try thinking about, things mostly used to build very boring line of business applications (think thousands of forms, huge grids, reports with charts, etc). Applications built with Ext JS can easily dwarf the framework itself; the biggest I've seen personally was ~30 mb of minified ES5 JavaScript.

...and it worked in IE8, BTW. :)
