What is ObjectOriented

Object Oriented Programming (OOP)

Object Oriented Programming (OOP) is a programming paradigm that revolves around the concept of objects. In OOP, objects are instances of classes, which are templates for creating objects. Each object has its own set of attributes (data) and methods (functions) that operate on the data.

Classes and Objects

In OOP, a class is a blueprint for creating objects. It defines the properties and behaviors that all objects of that class will have. An object, on the other hand, is an instance of a class. It represents a specific entity with its own unique set of data and methods.

Encapsulation

Encapsulation is the concept of bundling data and methods that operate on the data into a single unit, called an object. This helps in hiding the internal state of an object and only exposing the necessary information to the outside world. Encapsulation promotes data hiding and abstraction.

Inheritance

Inheritance is a mechanism in OOP that allows a class to inherit properties and behaviors from another class. This promotes code reusability and helps in creating a hierarchy of classes. Subclasses inherit the attributes and methods of their parent class, allowing for easy extension and modification.

Polymorphism

Polymorphism is the ability of an object to take on different forms or behaviors based on the context in which it is used. This allows for flexibility in programming and enables objects to be treated as instances of their parent class or as instances of their own class.

Abstraction

Abstraction is the process of hiding the implementation details of an object and only showing the essential features. It helps in simplifying complex systems by focusing on the relevant aspects and ignoring the irrelevant details. Abstraction allows for easier maintenance and modification of code.

Objects and Classes in React.Js and React Native

In React.Js and React Native, components are the building blocks of the user interface. Each component can be seen as an object, with its own set of properties and methods. Components can be reused, composed, and nested to create complex user interfaces.

Encapsulation in React.Js and React Native

Encapsulation in React.Js and React Native is achieved through the use of components. Each component encapsulates its own state and behavior, making it easier to manage and maintain. Components can be reused across different parts of the application, promoting code reusability.

Inheritance in React.Js and React Native

Inheritance in React.Js and React Native is achieved through component composition. Components can inherit properties and behaviors from other components, allowing for easy extension and modification. This promotes a modular and scalable approach to building user interfaces.

Polymorphism in React.Js and React Native

Polymorphism in React.Js and React Native is achieved through the concept of props. Props allow components to take on different behaviors based on the data passed to them. This enables components to be reused in different contexts, promoting flexibility and reusability.
