/**
* Creates a debounced function that delays invoking the provided function until after `wait` milliseconds have elapsed
* since the last time it was invoked. The debounced function will only be invoked once during the `wait` period.
*
* @param func - The function to debounce.
* @param wait - The number of milliseconds to delay.
* @param immediate - If `true`, the function will be invoked immediately on the leading edge instead of the trailing edge.
* If not provided, it is disabled by default.
* @returns A debounced function.
