Object Diagram

Make several variables and objects:

events = ['work', 'pizza', 'run']
squirrel = false
a = [events, squirrel]
c = {events, squirrel}
e = new Entry(events, squirrel)

Diagram

a[0] == c.events  //true -- same object
a.toString()  //"work,pizza,run,false"
c.toString()  //"[object Object]"
e.toString()  //"Entry: 3 events"
