Example breaks down, because React 16 have no `react/lib/*`

This example import update from react/lib/.

But in react 16 blog post:

There is no react/lib/* and react-dom/lib/* anymore

Yeah, my bad. That should be fixed in master now

For those who are upgrading from React 15 to React 16, used one of the deprecated examples in their code and end up here looking for help. The solution is simply to replace: import update from 'react/lib/update'; with import update from 'immutability-helper';
