Set Vs. WeakSet:

Set:
-- References To Objects Are Strong.
==> Object Can NOT Be Garbage Collected If There Is No Other Reference To It.
-- Contain Any Type Of Values.
-- Has size Property To Get Set Elements Count.
-- Has add(), delete(), has(), clear(), keys(), values(), entries(), forEach() Methods.
-- Set Is Iterable.


WeakSet:
-- References To Objects Are Weak.
==> Object Can Be Garbage Collected If There Is No Other Reference To It.
==> (i.e. The JS Engine Will Free The Memory Which Object Reference Was Pointing To).
-- Contain ONLY Object Type Values.
==> NO Primitive Values (e.g. int, boolean, string) Are Allowed.
-- Does NOT Have size Property To Get WeakSet Elements Count.
-- Has add(), delete(), has() Methods Only.
-- WeakSet Is Not Iterable.
