As we saw in the first chapter, plugins help extend the functionality of WordPress. It is simply the easiest way to add extra features or integrations to WordPress sites.
Plugins are what make WordPress sites feature-rich. Using plugins, you can take offsite backups, edit the .htaccess file, and even access the files present in the public folder of your web server. It can also be used for dropping the leftover database tables from poorly coded plugins.
This lesson will start with topics covering WordPress plugin development and end with an assignment to test your knowledge.
