+Extensible Data Notation or EDN for short is a format for serializing data.
+
+The notation is used internally by Clojure to represent programs and it also
+used as a data transfer format like JSON. Though it is more commonly used in
+Clojure land, there are implementations of EDN for many other languages.
+
+The main benefit of EDN over JSON and YAML is that it is extensible, which we
+will see how it is extended later on.

+Mint a JavaScript egyik követője, a CoffeeScript mindent megtesz azért, hogy olvasható, jól formázott és jól futó JavaScript kódot állítson elő, ami minden JavaScript futtatókörnyezetben jól működik.
