   /**
-   * Dispatches an action. It is the only way to trigger a state change.
+   * Collection of methods that allow declaration and validation of props that are
+   * supplied to React components. Example usage:
    *
-   * The `reducer` function, used to create the store, will be called with the
-   * current state tree and the given `action`. Its return value will
-   * be considered the **next** state of the tree, and the change listeners
-   * will be notified.
+   *   var Props = require('ReactPropTypes');
+   *   var MyArticle = React.createClass({
+   *     propTypes: {
+   *       // An optional string prop named "description".
+   *       description: Props.string,
    *
-   * The base implementation only supports plain object actions. If you want to
-   * dispatch a Promise, an Observable, a thunk, or something else, you need to
-   * wrap your store creating function into the corresponding middleware. For
-   * example, see the documentation for the `redux-thunk` package. Even the
-   * middleware will eventually dispatch plain object actions using this method.
+   *       // A required enum prop named "category".
+   *       category: Props.oneOf(['News','Photos']).isRequired,
    *
-   * @param {Object} action A plain object representing “what changed”. It is
-   * a good idea to keep actions serializable so you can record and replay user
-   * sessions, or use the time travelling `redux-devtools`. An action must have
-   * a `type` property which may not be `undefined`. It is a good idea to use
-   * string constants for action types.
+   *       // A prop named "dialog" that requires an instance of Dialog.
+   *       dialog: Props.instanceOf(Dialog).isRequired
+   *     },
+   *     render: function() { ... }
+   *   });
    *
-   * @returns {Object} For convenience, the same action object you dispatched.
+   * A more formal specification of how these methods are used:
    *
-   * Note that, if you use a custom middleware, it may wrap `dispatch()` to
-   * return something else (for example, a Promise you can await).
+   *   type := array|bool|func|object|number|string|oneOf([...])|instanceOf(...)
+   *   decl := ReactPropTypes.{type}(.isRequired)?
+   *
+   * Each and every declaration produces a function with the same signature. This
+   * allows the creation of custom validation functions. For example:
+   *
+   *  var MyLink = React.createClass({
+   *    propTypes: {
+   *      // An optional string or URI prop named "href".
+   *      href: function(props, propName, componentName) {
+   *        var propValue = props[propName];
+   *        if (propValue != null && typeof propValue !== 'string' &&
+   *            !(propValue instanceof URI)) {
+   *          return new Error(
+   *            'Expected a string or an URI for ' + propName + ' in ' +
+   *            componentName
+   *          );
+   *        }
+   *      }
+   *    },
+   *    render: function() {...}
+   *  });

+ * We listen for bubbled touch events on the document object.

+ * element. The symptoms were that if your mouse is not moving over something
+ * contained within that mount point (for example on the background) the

+ * register the `mousemove` on the document object, then it will of course

+ * top-level listeners to the document object only, at least for these
+ * movement types of events and possibly all events.
+ *
+ * @see http://www.quirksmode.org/blog/archives/2010/09/click_event_del.html

- *
- *  - 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.

- * We listen for bubbled touch events on the document object.
- *
- * Firefox v8.01 (and possibly others) exhibited strange behavior when
- * mounting `onmousemove` events at some node that was not the document
- * element. The symptoms were that if your mouse is not moving over something
- * contained within that mount point (for example on the background) the
- * top-level listeners for `onmousemove` won't be called. However, if you
- * register the `mousemove` on the document object, then it will of course
- * catch all `mousemove`s. This along with iOS quirks, justifies restricting
- * top-level listeners to the document object only, at least for these
- * movement types of events and possibly all events.
- *
- * @see http://www.quirksmode.org/blog/archives/2010/09/click_event_del.html
- *
- * Also, `keyup`/`keypress`/`keydown` do not bubble to the window on IE, but

+// UpdateQueue is a linked list of prioritized updates.
+//
+// Like fibers, update queues come in pairs: a current queue, which represents
+// the visible state of the screen, and a work-in-progress queue, which is
+// can be mutated and processed asynchronously before it is committed — a form
+// of double buffering. If a work-in-progress render is discarded before
+// finishing, we create a new work-in-progress by cloning the current queue.
+//
+// Both queues share a persistent, singly-linked list structure. To schedule an
+// update, we append it to the end of both queues. Each queue maintains a
+// pointer to first update in the persistent list that hasn't been processed.
+// The work-in-progress pointer always has a position equal to or greater than
+// the current queue, since we always work on that one. The current queue's
+// pointer is only updated during the commit phase, when we swap in the
+// work-in-progress.
+//
+// For example:
+//
+//   Current pointer:           A - B - C - D - E - F
+//   Work-in-progress pointer:              D - E - F
+//                                          ^
+//                                          The work-in-progress queue has
+//                                          processed more updates than current.
+//
+// The reason we append to both queues is because otherwise we might drop
+// updates without ever processing them. For example, if we only add updates to
+// the work-in-progress queue, some updates could be lost whenever a work-in
+// -progress render restarts by cloning from current. Similarly, if we only add
+// updates to the current queue, the updates will be lost whenever an already
+// in-progress queue commits and swaps with the current queue. However, by
+// adding to both queues, we guarantee that the update will be part of the next
+// work-in-progress. (And because the work-in-progress queue becomes the
+// current queue once it commits, there's no danger of applying the same
+// update twice.)
+//
+// Prioritization
+// --------------
+//
+// Updates are not sorted by priority, but by insertion; new updates are always
+// appended to the end of the list.
+//
+// The priority is still important, though. When processing the update queue
+// during the render phase, only the updates with sufficient priority are
+// included in the result. If we skip an update because it has insufficient
+// priority, it remains in the queue to be processed later, during a lower
+// priority render. Crucially, all updates subsequent to a skipped update also
+// remain in the queue *regardless of their priority*. That means high priority
+// updates are sometimes processed twice, at two separate priorities. We also
+// keep track of a base state, that represents the state before the first
+// update in the queue is applied.
+//
+// For example:
+//
+//   Given a base state of '', and the following queue of updates
+//
+//     A1 - B2 - C1 - D2
+//
+//   where the number indicates the priority, and the update is applied to the
+//   previous state by appending a letter, React will process these updates as
+//   two separate renders, one per distinct priority level:
+//
+//   First render, at priority 1:
+//     Base state: ''
+//     Updates: [A1, C1]
+//     Result state: 'AC'
+//
+//   Second render, at priority 2:
+//     Base state: 'A'            <-  The base state does not include C1,
+//                                    because B2 was skipped.
+//     Updates: [B2, C1, D2]      <-  C1 was rebased on top of B2
+//     Result state: 'ABCD'
+//
+// Because we process updates in insertion order, and rebase high priority
+// updates when preceding updates are skipped, the final result is deterministic
+// regardless of priority. Intermediate state may vary according to system
+// resources, but the final state is always the same.

If a work-in-progress render is discarded before\n// finishing, we create a new work-in-progress by cloning the current queue.\n//\n// Both queues share a persistent, singly-linked list structure. To schedule an\n// update, we append it to the end of both queues. Each queue maintains a\n// pointer to first update in the persistent list that hasn't been processed.\n// The work-in-progress pointer always has a position equal to or greater than\n// the current queue, since we always work on that one. The current queue's\n// pointer is only updated during the commit phase, when we swap in the\n// work-in-progress.\n//\n// For example:\n//\n//   Current pointer:           A - B - C - D - E - F\n//   Work-in-progress pointer:              D - E - F\n//                                          ^\n//                                          The work-in-progress queue has\n//                                          processed more updates than current.\n//\n// The reason we append to both queues is because otherwise we might drop\n// updates without ever processing them. For example, if we only add updates to\n// the work-in-progress queue, some updates could be lost whenever a work-in\n// -progress render restarts by cloning from current. Similarly, if we only add\n// updates to the current queue, the updates will be lost whenever an already\n// in-progress queue commits and swaps with the current queue. However, by\n// adding to both queues, we guarantee that the update will be part of the next\n// work-in-progress. (And because the work-in-progress queue becomes the\n// current queue once it commits, there's no danger of applying the same\n// update twice.)\n//\n// Prioritization\n// --------------\n//\n// Updates are not sorted by priority, but by insertion; new updates are always\n// appended to the end of the list.\n//\n// The priority is still important, though. When processing the update queue\n// during the render phase, only the updates with sufficient priority are\n// included in the result. If we skip an update because it has insufficient\n// priority, it remains in the queue to be processed later, during a lower\n// priority render. Crucially, all updates subsequent to a skipped update also\n// remain in the queue *regardless of their priority*. That means high priority\n// updates are sometimes processed twice, at two separate priorities. We also\n// keep track of a base state, that represents the state before the first\n// update in the queue is applied.\n//\n// For example:\n//\n//   Given a base state of '', and the following queue of updates\n//\n//     A1 - B2 - C1 - D2\n//\n//   where the number indicates the priority, and the update is applied to the\n//   previous state by appending a letter, React will process these updates as\n//   two separate renders, one per distinct priority level:\n//\n//   First render, at priority 1:\n//     Base state: ''\n//     Updates: [A1, C1]\n//     Result state: 'AC'\n//\n//   Second render, at priority 2:\n//     Base state: 'A'            <-  The base state does not include C1,\n//                                    because B2 was skipped.\n//     Updates: [B2, C1, D2]      <-  C1 was rebased on top of B2\n//     Result state: 'ABCD'\n//\n// Because we process updates in insertion order, and rebase high priority\n// updates when preceding updates are skipped, the final result is deterministic\n// regardless of priority. Intermediate state may vary according to system\n// resources, but the final state is always the same.\n\nvar UpdateState = 0;\nvar ReplaceState = 1;\nvar ForceUpdate = 2;\nvar CaptureUpdate = 3;\n\n// Global state that is reset at the beginning of calling `processUpdateQueue`.\n// It should only be read right after calling `processUpdateQueue`, via\n// `checkHasForceUpdateAfterProcessing`.\nvar hasForceUpdate = false;\n\nvar didWarnUpdateInsideUpdate = void 0;\nvar currentlyProcessingQueue = void 0;\nvar resetCurrentlyProcessingQueue = void 0;\n{\n  didWarnUpdateInsideUpdate = false;\n  currentlyProcessingQueue = null;\n  resetCurrentlyProcessingQueue = function () {\n    currentlyProcessingQueue = null;\n  };\n}\n\nfunction createUpdateQueue(baseState) {\n  var queue = {\n    expirationTime: NoWork,\n    baseState: baseState,\n    firstUpdate: null,\n    lastUpdate: null,\n    firstCapturedUpdate: null,\n    lastCapturedUpdate: null,\n    firstEffect: null,\n    lastEffect: null,\n    firstCapturedEffect: null,\n    lastCapturedEffect: null\n  };\n  return queue;\n}\n\nfunction cloneUpdateQueue(currentQueue) {\n  var queue = {\n    expirationTime: currentQueue.expirationTime,\n    baseState: currentQueue.baseState,\n    firstUpdate: currentQueue.firstUpdate,\n    lastUpdate: currentQueue.lastUpdate,\n\n    // TODO: With resuming, if we bail out and resuse the child tree, we should\n    // keep these effects.\n    firstCapturedUpdate: null,\n    lastCapturedUpdate: null,\n\n    firstEffect: null,\n    lastEffect: null,\n\n    firstCapturedEffect: null,\n    lastCapturedEffect: null\n  };\n  return queue;\n}\n\nfunction createUpdate(expirationTime) {\n  return {\n    expirationTime: expirationTime,\n\n    tag: UpdateState,\n    payload: null,\n    callback: null,\n\n    next: null,\n    nextEffect: null\n  };\n}\n\nfunction appendUpdateToQueue(queue, update, expirationTime) {\n  // Append the update to the end of the list.\n  if (queue.lastUpdate === null) {\n    // Queue is empty\n    queue.firstUpdate = queue.lastUpdate = update;\n  } else {\n    queue.lastUpdate.next = update;\n    queue.lastUpdate = update;\n  }\n  if (queue.expirationTime === NoWork || queue.expirationTime > expirationTime) {\n    // The incoming update has the earliest expiration of any update in the\n    // queue.
