I kept some places intact (search for @jsx) because they require other bigger changes:
- ref-01-top-level-api.md
- grunt/tasks/npm.js
- old blog posts (don't change those)
- examples/ folder, as they have their own package.json that rely on old dependencies (node-jsx, reactify) that haven't upgraded to 0.12
onInput has the advantage that it responds to repeated key events before
onKeyUp and is called when modifying the input without the keyboard
(such as pasting with the mouse).
Test Plan:
Opened the ballmer-peak example and docs homepage in Chrome and checked
that both examples update whenever the text is changed.
