Setting Up Magento 2 Development Environment With Docker & Warden on Windows

In Magento 2, events provide a mechanism for the system to signal when a particular action takes place. This enables developers to attach custom functionality at different stages of the application's lifecycle without modifying the core code. Events utilize the Observer design pattern, with observers monitoring these events and executing specific actions as needed.
