What is ng event?

Ng event refers to an Angular event, which is a mechanism for communicating between components and triggering actions based on user interactions or external factors. An Angular event is created by defining an event emitter property in a component, which can be used to emit events that can be listened to by other components. When an event is emitted, it sends a payload of data along with it, which can be used by the receiving component to perform some action.

Angular events are commonly used in scenarios where components need to communicate with each other without the need for direct coupling. Events can be triggered by user interactions, such as button clicks or form submissions, or by external factors, such as changes in data from an API or web socket.

In addition to defining custom events, Angular also provides a set of built-in events such as click, input, and submit, which can be used to handle common user interactions. Angular events play a crucial role in building reactive web applications that respond to user actions and external changes in real-time.
