// 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
