Space flight is no joke, and neither is this lab. You're going to need to create
two ES6 JS classes, Spaceship and CrewMember. These classes will pump out
instances that are by default unable to interact with one another. A space ship
will be inactive if it is created without a crew. And a crew member by default
will be hanging out in the Cantina looking for a ride if they were not put
inside a ship when it is initialized.
Crew members will also be unable to use their special abilities if they're not
assigned to a ship. For example, a pilot cannot engageWarpDrive if s/he is not
in a ship and, therefore, can't make the Kessel Run in less than twelve parsecs.
Crew members also should be unable to perform certain actions that their
positions are incapable of doing.
To have these two objects be aware of one another, we need to have the ship become aware of its crew members on instantiation. This will also require you to make sure a crew member becomes aware of their ship when they are added to it.
TLDR;
A ship cannot exist without a crew and an individual crew member can't use their special ability if not assigned to a ship.
