Is the jQuery version running on your WordPress site up to date?
Your theme and plugins, as well as WordPress itself, rely on jQuery. An out-of-date version may place your website at risk.
In this article, we will show you how to update jQuery to the latest version in WordPress.

Your WordPress website, as well as many plugins and themes you use, rely on JavaScript in combination with jQuery to create fast, interactive, and engaging features.
It’s important to keep jQuery up to date to maintain the security of your website. The latest version fixes bugs and vulnerabilities in previous versions that may place your site at risk.
If you are running the latest version of WordPress, then you don’t need to manually update jQuery. It’s automatically done for you.

But if you’re using an older version of WordPress, such as WordPress 5.4 or earlier, then it’s recommended that you do the update.

Also, if you’ve replaced the default WordPress jQuery with Google Library, then it won’t automatically update to the latest version.
Editor’s Note: it’s important to highlight that updating jQuery may break older plugin functionality, so after the update, you should test your website.

In most cases, it’s not an issue, but in case you run into problems, then you can easily return to the older version.
You can easily find the version of jQuery your website is running using the JavaScript console in your web browser.
First, you will need to visit your website and then open the JavaScript console. If you are using Google Chrome, then you can do this by selecting View » Developer » JavaScript Console from the menu.
