Alphabetising related posts

Hello,

I’m trying to alphabetise related posts. I’m using this code here to display related posts only from a category the pages belong to, which is output as a list:

function jp_only_rp_in_same_category( $categories, $post_id ) {
  $category_objects = get_the_category( $post_id );
  if ( ! empty( $categories ) ) {
      $categories = array_merge( 'categories', 'category_objects' );
      return $categories;
  }
  else {
    return $category_objects;
  }
}
add_filter( 'jetpack_relatedposts_filter_has_terms', 'jp_only_rp_in_same_category', 10, 2 );

This is how it looks:

Could you suggest whether if the best way of alphabetising this list is via PHP or Javascript/JQuery? I have tried using Javascript/JQuery with no luck.

I used this as a base: https://codepen.io/gabrieleromanato/pen/Cfpdu

Modified as such:

(function( $ ) {
	$(function() {
		$( "span", ".jp-relatedposts-post" ).sort(function( a, b ) {
			return $( a ).text() > $( b ).text(); 

		}).appendTo( ".jp-relatedposts-post" );

	});

})( jQuery );

Code is not my strength so I might have taken the wrong approach. Any help would be appreciated!

All the best,

Michael
