+ * Creates a debounced function that delays invoking `func` until after `wait`
+ * milliseconds have elapsed since the last time the debounced function was
+ * invoked. The debounced function comes with a `cancel` method to cancel
+ * 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.
+ *
+ * **Note:** If `leading` and `trailing` options are `true`, `func` is
+ * 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
+ * until to the next tick, similar to `setTimeout` with a timeout of `0`.
+ *
+ * See [David Corbacho's article](https://css-tricks.com/debouncing-throttling-explained-examples/)
+ * for details over the differences between `_.debounce` and `_.throttle`.

+ * Creates a throttled function that only invokes `func` at most once per

+ * method to cancel 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
+ * throttled function. Subsequent calls to the throttled function return the
+ * result of the last `func` invocation.
+ *
+ * **Note:** If `leading` and `trailing` options are `true`, `func` is
+ * invoked on the trailing edge of the timeout only if the throttled function
+ * is invoked more than once during the `wait` timeout.
+ *
+ * If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
+ * until to the next tick, similar to `setTimeout` with a timeout of `0`.
