Replicating the Google Wave layout in 100 lines of js code with UkiJS 17 years ago
There are lots of details missing. But replicating the whole wave was not the point of the demo.
The point was to show that we are not forced to use complex frameworks like SproutCore or GWT to build desktop-like app layouts. It's still possible to build them staying lean and simple.
And by staying simple you can move times faster. The demo was written in 2 evenings by a single developer.
