+     * delayed `func` invocations and a `flush` method to immediately invoke them.
+     * Provide `options` to indicate whether `func` should be invoked on the
+     * leading and/or trailing edge of the `wait` timeout. The `func` is invoked
+     * with the last arguments provided to the debounced function. Subsequent
+     * calls to the debounced function return the result of the last `func`
+     * invocation.

+     * invoked on the trailing edge of the timeout only if the debounced function
+     * is invoked more than once during the `wait` timeout.
+     *
+     * If `wait` is `0` and `leading` is `false`, `func` invocation is deferred

+/**
+ * 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.
