untracked allows reading the value of a signal without making such signal a dependency of our computed signal or effect.

In this example, increasing the counter doesn’t trigger a new computation of info. Only a new name does so

name = signal('Angular');
counter = signal(0);

info = computed(
    () =>
      `The name is now "${this.name()}" and the 
      counter value was ${untracked(this.counter)} when 
      the name changed.`
 );
