Backbone.js
Minimal structure for early client MVC. Taught the browser to think in models before React rewrote the rules.
Backbone faded when two-way binding frameworks and then virtual DOM libraries offered better ergonomics. It was the scaffolding era — useful, then obsolete. Its ideas linger in every router and model layer that followed.

Context
The browser ate the desktop
The web became the default delivery surface. LAMP and Rails made shipping cheap; Ajax made pages feel like apps; SOAP/SOA tried to enterprise-ify the wire. REST won by being debuggable with curl. This decade invented the modern product cadence — and the habit of treating every new framework as destiny.
