This way, the tree is traversed naturally and compactly. --- ### 3. **Minimal Dependencies** The client does not know the tree's structure and does not distinguish between node types. All the traversal and delegation logic is hidden inside the components. --- ### 4. **Extensibility Without Rewriting the Recursion** You can add a new node type, and the recursive operations keep working unchanged, because the interface stays the same. --- **Summary:** Composite makes recursive structures **transparent to the client**: the tree is processed as a single object, and the recursion is built into the architecture itself, without extra checks and conditions.For the reviewerNote to the moderator (optional)Visible only to the moderator.
