jQuery libraries in WordPress

A default WordPress installation comes in with a number of popular jQuery libraries to help developers extend functionality of their products by leveraging jQuery API.

WordPress themes and plugins are part of what makes this open-source content management system so popular on a web. To clarify, plugins help to extend a default functionality of WordPress, while WordPress themes allow users to modify appearance of their site.

Because many themes and plugins already rely on jQuery, WordPress includes some popular jQuery libraries by default. It allows developers to save a lot of time and effort when it comes to adding various functionality to their WordPress products.

This table contains a list of jQuery plugins, along with WordPress handles, included in a WordPress core by default.

Not to mention, WordPress also uses on some of these libraries. For instance, jQuery, along with jQuery libraries, are loaded and used by WordPress for dashboard user interface.

However, I suspect that this might change in the future.

Since WordPress are now moving towards web components based on React (think of the Block editor), I believe that admin UI will also be rebuilt using such components in the future versions of WordPress.

Yet, these are just my thoughts.

By the way, after running your site through Google PageSpeed Insights, you might notice render blocking issues due to the way a WordPress core loads jQuery. One of the possible solutions to fix it in WordPress is to move jQuery to footer.
