Final answer:
In Angular, data can be passed between components using input bindings, output events, and services.
Step-by-step explanation:
In Angular, exchanging data between components is accomplished through input bindings, output events, and services.
Input Bindings (Parent to Child):
To send data from a parent component to a child component, create an input property in the child.
Bind this property in the parent component by using square brackets, like <app-child [inputProperty]="parentData"></app-child>.
Output Events (Child to Parent):
To send data from a child component to a parent component, define an output property in the child.
Emit an event using EventEmitter when data needs to be sent.
Capture this event in the parent component by using parentheses, like <app-child (outputEvent)="handleData($event)"></app-child>.
Using a Service:
A service is a singleton object shared across components.
Components can inject the service and use it to share and exchange data.
This provides a centralized place for data management, facilitating communication between components.
These methods offer flexibility based on the specific requirements and relationships between components in an Angular application.
