Decorators between Class-based & Prototype-based programming languages

Implementing the decorator pattern will differ between Class-based and Prototype-based programming languages because of the difference in their nature. I will talk in this article about implementing the decorator pattern in both Javascript and C# programming languages. And consider some real-life scenarios to use them.

The difference between OOP and Prototype languages centralize around the reuse principle (Known as inheritance), its performed via a process of reusing objects (Known as prototype inheritance) in Prototype-based programming languages and via a process of reusing the classes of objects or blueprints of objects (Known as class inheritance).

The decorator is a design pattern that allows behavior to be added to an object in a dynamic way without having to change the implementation of that object. The decorator is considered as Structural design pattern. And an important note is that the decorator follows the Open-Closed Principle.

Implementing the decorator pattern will differ between Class-based and Prototype-based programming languages because of the difference in their nature. I will talk in this article about implementing the decorator pattern in both Javascript and C## programming languages. And consider some real-life scenarios to use them.

Decorator in C#

Decorators in C## can be applied using two methods:

1- Inheriting from a target class and have a setter method to set that target class instance inside the decorator or bypassing the target class as a dependency to the decorator class through the constructor. Then in the overridden functions, we call the target class function with additional decoration. The next UML explains that:

C Language is an evergreen language and is used widely across different industries, This C programming is a must for students and working professionals to become a great Software Engineer especially when they are working in Software Development Domain. Great Learning brings you this live session on "Introduction to C". In this live session, we will be covering major concepts in C Programming such as Different Variables, Different Data Types that are being used, its Operators, Flow control statements, Structure, and lot more.

Subtle differences with closure on loop variables in different programming languages (C# and JavaScript as examples). Closure is not a new concept. It was first introduced in the 1970s and is now available in most of the programming languages. I am sure most developers are familiar with it and use it on a regular basis. Here are some quick tests to check our understandings — can you tell the output for the four cases below in JavaScript and C#.

In this article, I am going to share some of the best courses to learn C# or C-Sharp in 2020. These courses are suitable for both beginners and experienced programmers who want to fill gaps in their C# knowledge.

C++ is general purpose, compiled, object-oriented programming language and its concepts served as the basis for several other languages such as Java, Python, Ruby, Perl etc.
