-This works for any object, as well as arrays.  It iterates over the keys of an object.
+For arrays in ES5, we can use Array.forEach():
+<lang JavaScript>"alpha beta gamma delta".split(' ').forEach(
+  function (x) {
+    console.log(x);
+  }
+);</lang>
+Output:
+<pre>alpha
+beta
+gamma
+delta</pre>
+More generally, the following works for any object, including an array.  It iterates over the keys of an object.
 <lang JavaScript>for (var a in o) {
     print(o[a]);
