Clojure uses persistence collections such as list, vector and map to #make copy efficient.
List is constructed as a singly linked list. It allows sequential access, but random access is forbidden. List could only point to another list or to itself.
Vector is constructed as a 202112121746. It allows sequential access as well as random access by referring to its index number.
Map is constructed as a 202112122035. It allows only random access by referring to the key stored in it.
