Explore React setState idiom of using a function instead of an object to update state

	/*
	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.
