| Simple javascript to explore the React stateState function paradigm | |
| node react_state_fn_upd_explore.js | |
| Explore the second form of setState() that accepts a function rather than an | |
| object. This is needed because React can batch state updates and | |
| asynchronous state updates mean you need a function that receives its | |
| current value before using values from it to set the next state | |
| values. |
