Sometimes, we learn lot of bigger things but miss on small learnings. I want to create small posts on vanilla JS to do things without libraries or frameworks on simple pages.
It is very easy to count number of elements using jquery. First we will see it in jQuery and then on vanilla JS.
<ul>
<li class="li-node">Children 1</li>
<li class="li-node">Children 2</li>
<li class="li-node">Children 3</li>
<li class="li-node">Children 4</li>
<li class="li-node">Children 5</li>
</ul>
Count using jQuery
$('.li-node').length;
Count using Vanilla JS
document.querySelectorAll('.li-node').length;
document.querySelectorAll
select all the elements with class name and returns an array of html element, then we can use the array length
property to find the count.
Hope you learned a simple trick in vanilla JS 😎
