   + if (array/array) case: the default behavior is returning the **concatenate array**, in order to handle more complex user case, we could use helpers **modification types**(insertType, insertFisrtType, insertLastType, insertBeforeMatchType, insertAfterMatchType, removeType, removeFirstType, removeLastType, removeMatchType);

-* `func mergeType(data) => object` return immutable array with deeply merged items.
