+ * Iterates over elements of a collection, executing the callback for each
+ * element. The callback is bound to `thisArg` and invoked with three arguments;
+ * (value, index|key, collection). Callbacks may exit iteration early by
+ * explicitly returning `false`.
+ *
+ * Note: As with other "Collections" methods, objects with a `length` property
+ * are iterated like arrays. To avoid this behavior `_.forIn` or `_.forOwn`
+ * may be used for object iteration.

+ * @param {Array|Object|string} collection The collection to iterate over.
+ * @param {Function} [callback=identity] The function called per iteration.
+ * @param {*} [thisArg] The `this` binding of `callback`.
+ * @returns {Array|Object|string} Returns `collection`.
+ * @example
+ *
+ * _([1, 2, 3]).forEach(function(num) { console.log(num); }).join(',');
+ * // => logs each number and returns '1,2,3'
+ *
+ * _.forEach({ 'one': 1, 'two': 2, 'three': 3 }, function(num) { console.log(num); });
+ * // => logs each number and returns the object (property order is not guaranteed across environments)
