The Store should never throw an Error without also emitting an event. Otherwise Store errors will be invisible to users, but the downstream errors they cause will be reported as bugs. (For example, github.com/facebook/react/issues/21402)
Emitting an error event allows the ErrorBoundary to show the original error.
Throwing is still valuable for local development and for unit testing the Store itself.
* import * as React from "react";
This is the correct way to import React from an ES module since the ES
module will not have a default export. Only named exports.
* import * as ReactDOM from "react-dom"
* Update Flow to 0.84
* Fix violations
* Use inexact object syntax in files from fbsource
* Fix warning extraction to use a modern parser
* Codemod inexact objects to new syntax
* Tighten types that can be exact
* Revert unintentional formatting changes from codemod
