- * 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`.

- * @param {Function} func The function to debounce.
- * @param {number} [wait=0] The number of milliseconds to delay.

- * Specify invoking on the leading edge of the timeout.
- * @param {number} [options.maxWait]
- * The maximum time `func` is allowed to be delayed before it's invoked.

- * 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`.
- *
