Debouncing and throttling library optimizes event handling by intelligently delaying or limiting function execution. This prevents overwhelming user interfaces and unnecessary server requests, especially for fast-paced events like scrolling, typing, or button clicks. Choose between debouncing for single, final execution after a pause, or throttling for consistent function calls within a set interval. Leverage this library to enhance performance and responsiveness in your web applications.

Usage

npm install debouncing --save
import { debounce, throttle } from "debouncing";

const onResize = (event) => {
  console.log("height", window.innerHeight);
  console.log("width", window.innerWidth);
};

/**
 * In the debouncing technique, no matter how many times the user fires the
 * event, the attached function will be executed only after the specified
 * time once the user stops firing the event.
 *
 * Returns a function, that, as long as it continues to be invoked, will not
 * be triggered. The function will be called after it stops being called for
 * N milliseconds.
 * @param {!Function} func The function to execute.
 * @param {number=} timeout The timeout in milliseconds.
 * @return {!Function} Returns a function, that, as long as it continues
 *     to be invoked, will not be triggered.
 */
window.addEventListener("resize", debounce(onResize, 250), false);
