 /**
  * 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 an options object 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
