Just like we did in the previous chapter, when we logged $event, you can do the same with #inputElementRef.

Playground: Change the method changeTitle so it will receive the whole element reference and log it to the console:

src/app/input-button-unit/input-button-unit.component.html

<input #inputElementRef
       [value]="title"              
       (keyup.enter)="changeTitle(inputElementRef)">

<button (click)="changeTitle(inputElementRef)">
  Save
</button>

changeTitle(inputElementReference) {
  console.log(inputElementReference);
  this.title = inputElementReference.value;
}

Don't forget to put the code back the way it was after you're finished experimenting! It's best to pass to a method exactly the value it needs, instead of the whole object.
