Previous Question

Debouncing is a technique to limit the rate at which a function is executed. It ensures that the function is only called after a specified delay has passed since the last time it was invoked.

<!-- BEGIN COPY / PASTE -->
        function debounce(func, delay) {
            let timeoutId;
            return function(...args) {
                clearTimeout(timeoutId);
                timeoutId = setTimeout(() => func.apply(this, args), delay);
            };
        }

        // Example usage:
        const debouncedFunction = debounce(() => console.log("Function executed!"), 300);

        // Call the debounced function multiple times
        debouncedFunction();
        debouncedFunction();
        debouncedFunction();
        // "Function executed!" will be logged only once, 300ms after the last call
        <!-- END COPY / PASTE -->

Additional Comment:

The "debounce" function takes two arguments: the function to debounce and the delay in milliseconds.
It returns a new function that, when invoked, clears the previous timeout and sets a new one.
The function will only execute after the specified delay has passed since the last call.
This is useful for optimizing performance in scenarios like window resizing or button clicks.
