What are the limitations of declaration merging in TypeScript?

Declaration merging in TypeScript allows you to combine multiple declarations into a single definition. However, there are limitations such as conflicts between types, merging only certain types of declarations, and issues with namespaces.

Can you give an example of a conflict that might occur?

Sure! If you have two interfaces with the same name but different properties, TypeScript will merge them. However, if the properties have conflicting types, it will result in an error.

How can I resolve these conflicts?

You can resolve conflicts by ensuring that the properties have compatible types or by using intersection types to combine them without conflicts.

Are there any best practices for using declaration merging?

Yes, it's best to keep declarations clear and avoid merging types that could lead to confusion. Use namespaces wisely and document your code to clarify intent.
