How do you emit events from a child to parent component?
This probes unidirectional data flow and child-to-parent event emission. In Vue, call $emit with a named event and payload; in Angular, use @Output with EventEmitter and emit the query. A red flag is suggesting two-way binding or direct parent mutation.
This checks your understanding of unidirectional data flow and child-to-parent event emission. In Vue, declare emits with defineEmits or use $emit, then listen via @event in the parent template. In Angular, expose an @Output EventEmitter, call emit in the child, and bind with (eventName) in the parent. A red flag is recommending two-way binding or direct parent mutation, which violates component encapsulation.
