Let's say a library developer Bob builds a module/library that exports a reducer and and action. He publishes the module to npm:

const INITIAL_STATE = { timesPoked : 0 };

export function makeSharedModuleAction(payload) {
  return { 'type': 'POKE', payload };
}

export function sharedModuleReducer(state = INITIAL_STATE, action) {

const winsIfSwitched = [];
const winsIfStayed = [];

function monty () {
  const doorWithCar = Math.floor(Math.random() * 3);
  const guessedDoor = Math.floor(Math.random() * 3);

  // Host removes a door that...
  const removedDoor = [0,0,0].reduce((result, n, index) => {
    // 1) contestant didn't pick and...

How do I React Component?

A variation with an unnecessary const

...since nothing in that file should be accessing that 'MyComponent' except the export.

Also that react import is very confusing though. Why do I need it? I don't reference that variable anywhere... oh wait some tool compiles the JSX for me at some point into React.createElement or whatever. Very opaque:
