Javascript without javascript
summary
Demonstrates that Ruby libraries compile to browser JavaScript using opal and webpack, lands a working local Sass runtime called offline sass club after several hundred string-replace patches, rewrites parts of Sass and opal, and converts ~3,000 test assertions so the suite runs in every modern browser with web workers (IE10 excluded). Resulting artifact is functional but heavy — ~2.7 MB of JS — and motivates moving to WebAssembly for much faster startup and smaller delivery.
