Angular - Component Interaction

Given this child component code:

@Output() change = new EventEmitter<number>();
updateValue() {
  this.change.emit(42);
}

What will the parent component receive when updateValue() is called?

AAn event with value 42

BAn event with value 'updateValue'

CNo event emitted

DAn error because emit needs a string

Step-by-Step Solution

Solution:

Step 1: Understand what emit does
The emit method sends the given value (here 42) as an event payload to the parent.
Step 2: Check the emitted value type
The emitter is typed as number and emits 42, so the parent receives 42.
Final Answer:
An event with value 42 -> Option A
Quick Check:
emit(42) sends 42 to parent [OK]

Quick Trick: emit(value) sends that value to parent [OK]
