Plugins are the powerhouse of WordPress—offering customization, flexibility, and endless opportunities. But how do you go from zero to launching a fully functional plugin? Let’s break it all down. 🔎 What is a WordPress Plugin? A WordPress plugin is a piece of software that “plugs into” your WordPress site. It allows you to extend functionality without modifying core files. Whether you’re adding contact forms, SEO features, or custom integrations, plugins make it possible. Some plugins are simple, others complex. The beauty lies in flexibility: if WordPress doesn’t do something out-of-the-box, you can develop your own WordPress plugin to make it happen. 🚀 Why Learn WordPress Plugin Development?
