manager is an object of Employee, supervisor and name are attributes of Employee,
manager.supervisor is a boss object,
So manager.supervisor.name is equivalent to boss.name
While boss.name is 111 and manager.name is 222
So manager.supervisor.name is 111

This is one way JavaScript builds classes.
Use the constructor Employee to build, which are the attributes.

The next few sentences are creating instances and showing their relationship.
