Random slide order in slick sider

I am going to show how we can randomize slick slider order so that every time the page refreshes slide shows differently.

Our old slider activation code is something like this

$('.raaa_hero_slider').slick({
	dots: false,
	infinite: true,
	speed: 300,
	slidesToShow: 1,
	slidesToScroll: 1,
	autoplay: true,
	autoplaySpeed: 3000,
	arrows: false,
	fade: true,
	cssEase: 'linear',
	pauseOnHover: false
});

Now, we are going to add a magic spell. Thanks to zexeder for this gist

$.fn.randomize = function (selector) {
	var $elems = selector ? $(this).find(selector) : $(this).children(),
		$parents = $elems.parent();

	$parents.each(function () {
		$(this).children(selector).sort(function (childA, childB) {
			// * Prevent last slide from being reordered
			if($(childB).index() !== $(this).children(selector).length - 1) {
				return Math.round(Math.random()) - 0.5;
			}
		}.bind(this)).detach().appendTo(this);
	});

	return this;
};

Now our final code will be look like this

$.fn.randomize = function (selector) {
	var $elems = selector ? $(this).find(selector) : $(this).children(),
		$parents = $elems.parent();

	$parents.each(function () {
		$(this).children(selector).sort(function (childA, childB) {
			// * Prevent last slide from being reordered
			if($(childB).index() !== $(this).children(selector).length - 1) {
				return Math.round(Math.random()) - 0.5;
			}
		}.bind(this)).detach().appendTo(this);
	});

	return this;
};
// adding randomize() function before slider active
$('.raaa_hero_slider').randomize().slick({
	dots: false,
	infinite: true,
	speed: 300,
	slidesToShow: 1,
	slidesToScroll: 1,
	autoplay: true,
	autoplaySpeed: 3000,
	arrows: false,
	fade: true,
	cssEase: 'linear',
	pauseOnHover: false
});
