1. No need for dfsIterative; integrate it directly into the dfs method. 2. Allow for public configuration of setLoopType. 3. Replace subTreeAdd with subTreeForeach for improved clarity and flexibility; provide a callback for enhanced versatility. 4. Standardize the naming of certain methods and parameters.

## Code design
### Adhere to ES6 standard naming conventions for APIs.
Standardize API conventions by using 'add' and 'delete' for element manipulation methods in all data structures.
Opt for concise and clear method names, avoiding excessive length while ensuring explicit intent.
### Object-oriented programming(OOP)
By strictly adhering to object-oriented design (BinaryTree -> BST -> AVLTree -> TreeMultiset), you can seamlessly
inherit the existing data structures to implement the customized ones you need. Object-oriented design stands as the
optimal approach to data structure design.
