What is debounce in JavaScript?

Can you explain what debounce means in JavaScript?

Sure! Debounce is a programming technique used to limit the rate at which a function is executed. It ensures that a function is only called after a certain amount of time has passed since it was last invoked.

Why is debounce important in web development?

Debounce is important because it helps improve performance by preventing excessive function calls, especially in scenarios like handling user input or window resizing.

Can you give me an example of how to implement debounce?

Absolutely! Here's a simple example:

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

This function will delay the execution of func until after delay milliseconds have passed since the last time it was invoked.

What are some common use cases for debounce?

Common use cases include handling input events in forms, resizing windows, and scrolling events to improve performance and user experience.
