我的这个JS函数的ClojureScript翻译是惯用的吗？

Question

I am trying to assess whether my CLJS function declaration is idiomatic. Here is my attempt to convert a JS function into its corresponding CLJS function. (You can ignore the actual content of the function).

JavaScript function:

var dir = require('node-dir');

function jsFunc(path) {
    dir.files(path, function(err, files) {
        if (err) throw err;
        files = files.filter(function (file) {
           return file.endsWith('.dec');
        });

        console.log(files);
    });
}

My translation into ClojureScript:

(defn cljs-func [input-path]
  (let [dir (node/require "node-dir")]
    (.files dir input-path (fn [err files] 
                               (println (.filter files (fn [file] (.endsWith file ".dec")))))))

Seems fine to me. As @cfrick points out in the comments, you could make the code more terse in some ways (eg using an anonymous function, which is idiomatic where its a single-use and relatively simple). Once you start having multiple arguments, I think it starts to make more sense to have an inline function declaration for readability's sake.

I would also second @cfrick's advice on preferring clojurescript's version of filter and any other function calls of this sort. I think the less you directly depend on the host environment, the more portable your code becomes. Certainly a trend that many clojure projects are going in these days with the introduction of reader conditionals in clojure 1.7.
