Define/Explain DOM Custom Events

DOM custom events are user-defined events that can be created, dispatched, and listened to within the Document Object Model (DOM) of a web page. They enable communication between different parts of a web application by allowing developers to define their own event types and handle them accordingly.

Define/Explain How to Create Custom Events

To create a DOM custom event, you first instantiate a new CustomEvent object, passing in the event type and optional data. Then, you dispatch this event on a DOM element using the `dispatchEvent()` method, making it available for other parts of the application to listen and respond to.

Explain Why DOM Custom Events are Used?

DOM custom events are used to facilitate communication between different parts of a web application in a decoupled and flexible manner, enabling better modularity and maintainability of code. They allow developers to define and handle custom event types, promoting a more organized and extensible architecture for complex web applications.

Summary

DOM custom events, which are user-defined events within the Document Object Model of a web page. They enable developers to create and dispatch custom event types for communication between various parts of a web application, promoting modularity and flexibility in architecture.
