Restcase: Backbone Without Backbone
Victor extracted Backbone's Model, Collection, and Events into a standalone library. The data layer works. The REST part is empty stubs. The pattern is becoming clear.

parse.js: What Was Left Behind
A line-by-line comparison of Victor's parse.js against Angular 1.4.1's $parse. The extraction was almost verbatim — and incomplete in ways that matter.

Mobie: The Framework That Almost Was
Victor didn't just use AngularJS — he built a mobile UI framework to compete with Ionic. 289 commits, 79 versions, a GitHub organization, a docs site. Then silence.
