    The Proxy Design Pattern is a structural design pattern that provides a surrogate or placeholder for another object to control access to it. This pattern is useful when you want to add an extra layer of control over access to an object. The proxy acts as an intermediary, controlling access to the real object1.

    Key Components

    1. Subject: An interface or abstract class that defines the common interface shared by the RealSubject and Proxy classes. It declares the methods that the Proxy uses to control access to the RealSubject1.

    2. RealSubject: The actual object that the Proxy represents. It contains the real implementation of the business logic or the resource that the client code wants to access1.

    3. Proxy: Acts as a surrogate or placeholder for the RealSubject. It controls access to the real object and may provide additional functionality such as lazy loading, access control, or logging1.

    What is proxy design pattern?
    The proxy acts as an intermediatory layer between the client and the real object and hence can control the access to the real object, add additional functionality, and even restrict client access. It is also known as Surrogate Pattern. When Will We Need Proxy Design Pattern?

    What is a proxy pattern in object oriented programming?
    The Proxy pattern provides a surrogate or placeholder object for another object and controls access to this other object. In object-oriented programming, objects do the work they advertise through their interface (properties and methods). Clients of these objects expect this work to be done quickly and efficiently.

    What is a proxy pattern in JavaScript?
    With the Proxy pattern, we don't want to interact with this object directly. Instead, a Proxy object intercepts the request, and (optionally) forwards this to the target object - the person object in this case. In JavaScript, we can easily create a new proxy by using the built-in Proxy object.

    What is a proxy pattern in C#?
    Proxy pattern in C#. Full code example in C# with detailed comments and explanation. Proxy is a structural design pattern that provides an object that acts as a substitute for a real service object used by a client. A proxy receives client requests, does some work (access control, caching, etc.) and then passes the request to a service object.

    When to use a proxy pattern?
    Understanding how to use a pattern is important. Understanding when to use it is critical. Let’s talk about when to use the Proxy pattern: When we want a simplified version of a complex or heavy object. In this case, we may represent it with a skeleton object which loads the original object on demand, also called as lazy initialization.

    What is the difference between decorator pattern and proxy pattern?
    Decorator Pattern: It is a structural design pattern that acts as a wrapper that adds additional functionality and responsibilities to objects, whereas the Proxy pattern only controls the access to the object by acting as an intermediatory layer between the client and the implementation.
