Come let's explore much deeper into the types of Components present in React JS:

1. Functional Components:
Functional components, also known as stateless components, are JavaScript functions that accept props (short for properties) and return React elements. They are simple and concise, focusing solely on rendering UI based on the input props. With the introduction of React hooks, functional components gained more prominence, as they can now manage state and lifecycle methods using hooks like useState and useEffect.

2. Class Components:
Class components are ES6 classes that extend React. Component. Historically, class components were the primary way of creating stateful components in React. They include a render method that returns the UI representation based on the component's state and props. However, with the rise of functional components and hooks, the usage of class components has diminished, though they are still prevalent in legacy codebases.

3. Presentational Components:
Presentational components, also known as dumb or pure components, are primarily concerned with how things look. ...
... They receive data and callbacks via props and render UI elements accordingly. These components are devoid of any business logic or state management and focus solely on presentation. Presentational components are highly reusable and facilitate better separation of concerns in React applications.

4. Container Components:
Container components, also referred to as smart components, are responsible for managing state and behavior. Unlike presentational components, container components are concerned with how things work rather than how they look. They encapsulate the application logic, handle data fetching, and pass down props to presentational components. Container components facilitate a clear separation between UI and application logic, promoting maintainability and testability.

5. Higher-Order Components (HOCs):
Higher-order components (HOCs) are a design pattern in React that enables component composition and code reuse. A HOC is a function that takes a component and returns a new enhanced component with additional functionality. HOCs are commonly used for cross-cutting concerns such as authentication, logging, or routing. They promote code reuse and enhance the composability of React components.

6. Render Props Components:
Render Props is another design pattern in React that involves passing a function as a prop to a component, allowing the component to render content based on the provided function. Render Props components are highly flexible and enable component composition without the need for higher-order components. They facilitate code reuse and provide a powerful mechanism for sharing behavior between components.

Conclusion:
The React offers a diverse array of components catering to different aspects of UI development. By understanding the various types of components in React, developers can leverage them effectively to build scalable, maintainable, and reusable UI components. Whether it's functional components, class components, presentational components, container components, higher-order components, or render props components, each type serves a distinct purpose in the React ecosystem, contributing to the overall success of React applications.
