A plugin is computer software or also commonly known as an extension/add-on that adds a specific/new feature to an existing computer program. It allows you to add more advanced eCommerce features without disturbing the main code. It is also called an add-on or extension.
Software developers deliberately include a plugin architecture in their program because it helps them add more functionality as and when required. In simple words, plugins let software developers introduce those features that they did not anticipate during the planning stage.
Plugins have been in use since the 90s, with Adobe Photoshop being one of those first programs that allowed extensive use of plugins. Plugins are invaluable, especially for those who have zero knowledge about coding. These plugins can aid your blog posts to rank better and help in many other ways, such as displaying YouTube videos on your website, adding share buttons to your blogs, and customizing your website's fonts.
Software developers continuously work on their plugins and push updates periodically to fix hidden bugs, introduce advanced functions, and give an immersive experience to users.
