  • Clojure, the core data structures aren't mutable

Clojure Data Structures

Clojure has two types of expressions atoms and collections

ATOMS

Atoms represent Primitive Types in other languages, like:
Numbers, Strings, Boolean, Nil, Symbols, Keywords

View clojure2.clj
;; eg: symbols in clojure, points to a verb or other values
;; when clojure evaluates a symbol it looks up that symbols meaning
inc
;; refer to symbols without evaluating its meaning
;; ' escapes a expression. Quote anything and get it back exactly
;; the same
'inc
