JavaScript Debounce and throttling are two simple, yet powerful techniques we can use in JavaScript applications to improve performance. In this article, I will introduce debounce and throttle in JavaScript, and discuss why we need to use them. The concept of debounce is pretty straightforward.

JavaScript Debounce vs. Throttle

My short explanation of debounce:

It’s from an <a href="https://www.perssondennis.com/articles/react-hooks-use-throttled-value-and-use-throttled-function#user-content-what-is-throttle-and-debounce" target="_blank" rel="noopener nofollow">article about debounce and throttle and React</a>.

Can anyone explain what the <code>args</code> do int he fn that the author created?
<pre><code>function debounce(callback, delay = 1000) {
 var time;
 return (...args) => {
 clearTimeout(time);
 time = setTimeout(() => {
 callback(...args);
 }, delay);
 };
}
</code></pre>
I removed them from the stackblitz example and it made no difference.
