/**
 * 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.
 *
 * @param {T} func - The function to debounce.
 * @param {number} [waitArg=0] - The number of milliseconds to delay.
 * @param {DebounceSettings} [options={}] - The options object.
 * @return {DebouncedFunction<T>} Returns the new debounced function.
 *
 * @example
 * // Avoid costly calculations while the window size is in flux.
 * window.addEventListener('resize', debounce(calculateLayout, 150));
