/*
  - Set vs WeakSet
  "
    The WeakSet is weak,
    meaning references to objects in a WeakSet are held weakly.
    If no other references to an object stored in the WeakSet exist,
    those objects can be garbage collected.
  "
  --
  Set     => Can Store Any Data Values
  WeakSet => Collection Of Objects Only
  --
  Set     => Have Size Property
  WeakSet => Does Not Have Size Property
  --
  Set     => Have Keys, Values, Entries
  WeakSet => Does Not Have clear, Keys, Values And Entries
  --
  Set     => Can Use forEach
  WeakSet => Cannot Use forEach

  Usage: Store objects and removes them once they become inaccessible
