/**
 * 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 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 are Value Objects: they implement `equals()`
 * and `hashCode()`.

   Access to dispatch is provided to the factory so selectorFactories can bind actionCreators
  outside of their selector as an optimization. Options passed to connectAdvanced are passed to
  the selectorFactory, along with displayName and WrappedComponent, as the second argument.
   Note that selectorFactory is responsible for all caching/memoization of inbound and outbound
  props. Do not use connectAdvanced directly without memoizing results between calls to your
  selector, otherwise the Connect component will re-render on every state or props change.

  // the developer's perspective, the error is uncaught.
  //
  // To preserve the expected "Pause on exceptions" behavior, we don't use a
  // try-catch in DEV. Instead, we synchronously dispatch a fake event to a fake
  // DOM node, and call the user-provided callback from inside an event handler
  // for that fake event. If the callback throws, the error is "captured" using
  // a global event handler. But because the error happens in a different

/**
 * Summary of `DOMEventPluginSystem` 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
 *    ReactDOMEventListener, 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 `EventPluginRegistry`, which in turn will ask plugins if they want
 *    to extract any synthetic events.
 *
 *  - The `EventPluginRegistry` will then process each event by annotating them with
 *    "dispatches", a sequence of listeners and IDs that care about that event.
 *
 *  - The `EventPluginRegistry` then dispatches the events.

        // a fallback, then we should always suspend/restart. SuspenseConfig applies to
        // this case. If none is defined, JND is used instead.

/**
 * @deprecated
 *
 * **We recommend using the `configureStore` method

 *

 *
 * **For more details, please read this Redux docs page:**
 * **https://redux.js.org/introduction/why-rtk-is-redux-today**
 *
 * `configureStore` from Redux Toolkit is an improved version of `createStore` that
 * simplifies setup and helps avoid common bugs.
 *
 * You should not be using the `redux` core package by itself today, except for learning purposes.
 * The `createStore` method from the core `redux` package will not be removed, but we encourage
 * all users to migrate to using Redux Toolkit for all Redux code.
 *
 * If you want to use `createStore` without this visual deprecation warning, use
 * the `legacy_createStore` import instead:
 *
