  /**
   * An extension of the "same-value" algorithm as [described for use by ES6 Map
   * and Set](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map#Key_equality)
   *
   * NaN is considered the same as NaN, however -0 and 0 are considered the same
   * value, which is different from the algorithm described by
   * [`Object.is`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/is).
   *
   * This is extended further to allow Objects to describe the values they
   * represent, by way of `valueOf` or `equals` (and `hashCode`).
   *
   * Note: because of this extension, the key equality of Immutable.Map and the
   * value equality of Immutable.Set will differ from ES6 Map and Set.
   *
   * ### Defining custom values
   *
   * The easiest way to describe the value an object represents is by implementing
   * `valueOf`. For example, `Date` represents a value by returning a unix
   * timestamp for `valueOf`:
   *
   *     var date1 = new Date(1234567890000); // Fri Feb 13 2009 ...
   *     var date2 = new Date(1234567890000);
   *     date1.valueOf(); // 1234567890000
   *     assert( date1 !== date2 );
   *     assert( Immutable.is( date1, date2 ) );
   *
   * Note: overriding `valueOf` may have other implications if you use this object
   * where JavaScript expects a primitive, such as implicit string coercion.
   *
   * For more complex types, especially collections, implementing `valueOf` may
   * not be performant. An alternative is to implement `equals` and `hashCode`.
   *
   * `equals` takes another object, presumably of similar type, and returns true
   * if the it is equal. Equality is symmetrical, so the same result should be
   * returned if this and the argument are flipped.
   *
   *     assert( a.equals(b) === b.equals(a) );
   *
   * `hashCode` returns a 32bit integer number representing the object which will
   * be used to determine how to store the value object in a Map or Set. You must
   * provide both or neither methods, one must not exist without the other.
   *
   * Also, an important relationship between these methods must be upheld: if two
   * values are equal, they *must* return the same hashCode. If the values are not
   * equal, they might have the same hashCode; this is called a hash collision,
   * and while undesirable for performance reasons, it is acceptable.
   *
   *     if (a.equals(b)) {
   *       assert( a.hashCode() === b.hashCode() );
   *     }
   *
   * All Immutable collections implement `equals` and `hashCode`.

/**
 * Summary of `ReactBrowserEventEmitter` event handling:
 *
 *  - Top-level delegation is used to trap most native browser events. This
 *    may only occur in the main thread and is the responsibility of
 *    ReactEventListener, which is injected and can therefore support pluggable
 *    event sources. This is the only work that occurs in the main thread.
 *
 *  - We normalize and de-duplicate events to account for browser quirks. This
 *    may be done in the worker thread.
 *
 *  - Forward these native events (with the associated top-level type used to
 *    trap it) to `EventPluginHub`, which in turn will ask plugins if they want
 *    to extract any synthetic events.
 *
 *  - The `EventPluginHub` will then process each event by annotating them with
 *    "dispatches", a sequence of listeners and IDs that care about that event.
 *
 *  - The `EventPluginHub` then dispatches the events.
 *

 * - Deactivating events while rearranging the DOM, preventing blurs/focuses,
 *   while guaranteeing that afterwards, the event system is reactivated.
 * - Flushing a queue of collected DOM mutations to the main UI thread after a
 *   reconciliation takes place in a worker thread.
 * - Invoking any collected `componentDidUpdate` callbacks after rendering new

 * - (Future use case): Wrapping particular flushes of the `ReactWorker` queue

 * - (Future use case): Layout calculations before and after DOM updates.
