What is Events in Lightning Web Components?

Events in lightning web components (LWC) are mechanisms used to facilitate communication between different components within a Salesforce Lightning application. Events in LWC are built on the standard DOM Events API, which is a collection of APIs and objects available in every browser. These events allow components to send messages to each other, either as a parent-to-child, child-to-parent, or sibling-to-sibling communication.

Types of Events in LWC

1. Standard DOM Events:

   • These are the browser’s default events, such as click, input, change, etc. They are used to handle interactions like button clicks, form submissions, etc.

2. Custom Events:

   • LWC provides a CustomEvent interface to create and dispatch custom events. These events are used to send custom messages between components, allowing for more granular and controlled communication.
