Hi all, In Stuart Halloway's book (Programming Clojure) is a wonderful example of the succinctness of Clojure where he compares the Apache Commons implementation of the isBlank method ( http://commons.apache.org/lang/api-2.5/src-html/org/apache/commons/lang/StringUtils.html#line.227) with a Clojure equivalent which is a single line:
(defn blank? [s] (every? #(Character/isWhitespace %) s)) I have used this example a few times to show colleagues the difference between Java and Clojure and why (IMHO) the Clojure solution is so much nicer. Earlier today I looked at clojure.string and noticed that it had blank? in it and looking at the source ( https://github.com/clojure/clojure/blob/f30995c86056959abca53d0ca35dcb9cfa73e6e6/src/clj/clojure/string.clj#L225) I noticed that the actual implementation in Clojure is surprisingly similar to the Java one (verbose, several if's, a loop etc.) Is there any particular reason for this? It is performance? What is wrong with Stuarts example? (I just checked it and it correct as far as I can tell). And a second question: What other examples are people using to demonstrate the advantages of Clojure (in an elevator pitch style equivalent) TIA, Thomas -- You received this message because you are subscribed to the Google Groups "Clojure" group.
