Should we use throttling or debouncing for windows resize event?

Oh just figure it out that Drupal core JS already have debounce implementation which we should use for this, check core/misc/debounce.js, method Drupal.debounce().

yes and if not i will make a time ;)

i will try today evening to start with this and other one - de-bouncing related.

Oh damn 7 months already passed... where???

@woprrr check core/misc/debounce.js - this is the library we should use. There are many examples in Drupal core how to use it, for example core/modules/outside_in/js/offcanvas.js

For example something like this we need. Instead of

// Handling cropping when viewport resizes.
$(window).resize(function () {
  $(detailsParentSelector).each(function () {
    // Find only opened widgets.
    // ...
  });
});

Do something like this

var croppingResize = function () {
  $(detailsParentSelector).each(function () {
    // Find only opened widgets.
    // ...
  });
};

// Handling cropping when viewport resizes.
$(window).resize(function () {
  debounce(croppingResize, 250)
});

This basically says when window resize event is happening fire croppingResize function on each 250ms while resize events is going on.
