-// - array-processing functions similar to standard JS functions
-
-// Notes:
-// - this module provides JS standard methods similar to high-level functions in dojo/_base/array.js:
-// forEach, map, filter, every, some
-
-// Defined methods:
-// - take any valid lambda argument as the functional argument
-// - operate on dense arrays
-// - take a string as the array argument
-// - take an iterator objects as the array argument
