  1. As a variable whose current value selects the property
  2. As the literal property name nameПравильный ответ
  3. As a request to enumerate every property
  4. As a Symbol created for this access

Объяснение

Dot notation treats the identifier after the dot as the literal property name to access. It does not look up a variable named name, which is the behavior associated with a computed bracket expression.
