Frage 62

In the expression user.name, how does JavaScript interpret name?

As a variable whose current value selects the property
As the literal property name nameRichtige Antwort
As a request to enumerate every property
As a Symbol created for this access

Erklärung

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.
