What is debouncing in input handling?

Debouncing is a technique used to limit the rate at which a function is executed. It's commonly used in input handling to prevent excessive calls when a user types or interacts with a UI element.

Can you give me an example of how to implement debouncing in JavaScript?

Sure! Here's a simple example:

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

const handleInput = debounce(() => {
    console.log('Input processed!');
}, 300);

inputElement.addEventListener('input', handleInput);

Why is debouncing important for performance?

Debouncing improves performance by reducing the number of function calls, especially in scenarios like search inputs or window resizing, where events can fire rapidly.
