* @param {boolean} [options.trailing=true] Specify execution on the trailing edge of the timeout.
* @returns {Function} Returns the new throttled function.
* @example
*
* // avoid excessively updating the position while scrolling
* var throttled = _.throttle(updatePosition, 100);
* jQuery(window).on('scroll', throttled);
*
* // execute `renewToken` when the click event is fired, but not more than once every 5 minutes
* jQuery('.interactive').on('click', _.throttle(renewToken, 300000, {

How does lodash.throttle work?

lodash.throttle is a function that returns a new function that can be used to limit the rate at which a specified function can be called. It delays invoking the function until a specified amount of time has passed since the last time it was invoked, and it only allows it to be called once within that time period. This can be useful for improving performance and preventing excessive updates or requests.

import throttle from "lodash.throttle";

function handleScroll() {
  console.log("Scroll event triggered");
}

window.addEventListener("scroll", throttle(handleScroll, 1000));

In this example, the handleScroll function will be called no more than once per second due to the throttle function applied to it.
