Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

$.fn.changeElementType = function(newType) {
    var newElements = [];

    $(this).each(function() {
        var attrs = {};

        $.each(this.attributes, function(idx, attr) {
            attrs[attr.nodeName] = attr.nodeValue;
        });

/* Iterator for arrays of WordPress posts or `WP_Query`. 
 *
 * Simplifies "the loop" by automatically handling the `$post` global for each iteration 
 * (calling `the_post()`, `setup_postdata()` etc.) and makes sure to reset the global state when the loop has finished. 
 *
 * Usage:
 * Loop over ten last posts:
 * <?php foreach (new WPQueryIterator(array('post_type' => 'post', 'posts_per_page' => 10)) as $i => $p): ?>
 *    <?php the_title(); ?>
