### What we like

Simplifies the approach to adding attributes to HTML tags for dynamic features. Now uses fetch(). Makes it easy to implement features like infinite scroll, form post, search as you type, polling, and streaming responses. Still pretty minimal (11kb) and no dependencies.

### Tradeoffs

Lots of attributes littered all over your HTML, but that is the point.
