In jQuery, you can find the next, previous, and parent element using the <code>next()</code>, <code>prev()</code>, <code>parent()</code> and <code>closest()</code> functions. The equivalents in JavaScript are <code>nextElementSibling</code>, <code>previousElementSibling</code>, <code>parentElement</code> and <code>closest</code> attributes.
Refer to the following code snippet to find the next, previous, and parent element through jQuery and vanilla JavaScript:
<pre><code>// Find the next, previous, and parent element using jQuery
$(".blog-post").next();
$(".blog-post").prev();
$(".blog-post").parent();
$(".blog-post").closest('.post-wrapper');
</code></pre><pre><code>// Find the next, previous, and parent element using vanilla JavaScript
let blogPost = document.querySelector(".blog-post");
blogPost.nextElementSibling;
blogPost.previousElementSibling;
blogPost.parentElement;
blogPost.closest('.post-wrapper');
</code></pre>
