	/**
	 * 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`.
