How do I implement debouncing in my JavaScript code?

Debouncing is a technique used to limit the rate at which a function is executed. It ensures that a function is only called after a specified delay, preventing it from being called too frequently.

Can you show me a simple example of debouncing?

Sure! Here's a basic example:

function debounce(func, delay) {
    let timeout;
    return function(...args) {
        clearTimeout(timeout);
        timeout = setTimeout(() => func.apply(this, args), delay);
    };
}

const handleResize = debounce(() => {
    console.log('Window resized!');
}, 300);

window.addEventListener('resize', handleResize);

What are some common use cases for debouncing?

Common use cases include handling window resize events, search input fields, and button click events to prevent multiple submissions.

Are there any libraries that can help with debouncing?

Yes, libraries like Lodash provide a debounce function that you can use directly, making it easier to implement.
