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);
