In May 2004 WordPress released its version 1.2 called Mingus. In this version, WordPress came up with plugins for the first time. Now the main question: What is a plugin in WordPress?

A plugin is a package of codes that allows you to increase the functions of WordPress without editing the core of WordPress.

WordPress plugins are made up of PHP codes, images, CSS, and datascript.
