+/**
+ * Creates a flattened array of values by running each element in `collection`
+ * thru `iteratee` and flattening the mapped results. The iteratee is invoked
+ * with three arguments: (value, index|key, collection).
+ *
+ * @static
+ * @memberOf _
+ * @since 4.0.0
+ * @category Collection
+ * @param {Array|Object} collection The collection to iterate over.
+ * @param {Function} [iteratee=_.identity] The function invoked per iteration.
+ * @returns {Array} Returns the new flattened array.
+ * @example
+ *
+ * function duplicate(n) {
+ *   return [n, n];
+ * }
+ *
+ * _.flatMap([1, 2], duplicate);
+ * // => [1, 1, 2, 2]
