Tight Coupling Between Elements and Visitors:?

Short answer: Even though the pattern allows you to add new operations without modifying the element classes, you still need to ensure that visitors and elements are compatible.

Explain a bit more

This can lead to some level of coupling between visitors and element classes. Conclusion: The Visitor Pattern is an excellent choice when you need to separate the operations performed on a structure from the structure itself, particularly in cases where the structure is complex and may evolve over time. It allows you to introduce new operations without modifying existing object classes. However, it can become difficult to manage when you need to add new element types, as every visitor must be updated to handle the new type. This pattern is often used in scenarios like processing different kinds of products in a shopping cart, applying various types of discounts or taxes, or performing different transformations on elements of a composite structure.
