What is Communication?
Angular components can communicate with each other using @Input() and @Output() decorators. These decorators facilitate data exchange between parent and child components.
- @Input(): This decorator allows a parent component to pass data to a child component, enabling the child to receive and use the data.
- @Output(): This decorator allows a child component to emit events to a parent component, enabling the parent to respond to changes or actions within the child component.
