The Visitor [1] design pattern is one of the twenty-three well-known Gang of Four design patterns that describe how to solve recurring design problems to design flexible and reusable object-oriented software, that is, objects that are easier to implement, change, test, and reuse.
The use and mechanics of agents ensure this. One possible downside of the use of agents is that an agent is computationally more expensive than its direct call counterpart. With this in mind, one ought never to presume the use of agents in the double-dispatch and their application in visitor patterns.
The single-serving visitor pattern should be used when visitors do not need to remain in memory. This is often the case when visiting a hierarchy of objects (such as when the visitor pattern is used together with the composite pattern) to perform a single task on it, for example counting the number of cameras in a 3D scene.
Using a visitor is a complementary approach to doing something with a collection of objects. In particular, a core idea of the visitor pattern is that you can prescribe different operations for different polymorphic (or static) types you visit. Also, with the visitor pattern, different objects have control over traversal order.

TypeScript supports intersection types, [5] improving expressiveness of the type system and reducing potential class hierarchy size, demonstrated as follows.. The following program code defines the classes Chicken, Cow, and RandomNumberGenerator that each have a method produce returning an object of either type Egg, Milk, or number.
