ReactJS Components: Its Type

React JS has greatly transformed the way of developing online applications. In addition, this software tool provides great opportunities for developers and allows them to build applications in a seamless and efficient way. React JS ensures great data flow and allows you to design efficient and scalable web application solutions. To learn more about it, one can visit the React JS Course Online. Below are some of the significant features of React JS.

• Virtual DOM – Virtual DOM makes React JS much more efficient and productive. It is just a duplication of the real DOM and is useful for improving the application’s performance and keeping it consistent. Furthermore, it also facilitates the debugging and testing of React apps.
• Unidirectional Data Flow – React JS follows a unidirectional data flow and ensures that the data flows from the root component to the child components. Furthermore, the unidirectional data flow ensures predictability and provides the application with greater scalability.
• JSX – It is useful for writing HTML-like code within JavaScript which makes the code easier to manage and develop. JSX provides users with a great option for describing the components. Furthermore, it ensures compatibility with the browser and improves the readability of the codebase.
• React Hooks – These are class component features that are useful for simplifying the code structures. Some common examples of the React hooks are State, use Effect, and use Context. These features make React JS one of the best choices for building modern web applications.

Components of React JS

ReactJS comes with various components which act as the building blocks of the React applications. In addition, these components are reusable and self-contained units of the User Interface that require both the UI and the logic to manage and manipulate that UI. There are two types of components in react which are Functional components and Class components. You will be asked about the components in the React JS Advanced Interview Questions. Now let’s have a look at the description of these React JS components.

• Functional Components – The functional components are the primary thing you need to build reusable and modular UI components. In addition, they are just the JavaScript functions that get properties in input and return JSX as the output. The functional components offer a better and more realistic syntax in comparison to the class components. They don’t have any lifecycle methods and you can add them by simply implementing the React Hooks. Above all, they are easier to debug, read, and test.
• Class Components – The class components are useful for building reusable and interactive UI elements. In addition, they are the JavaScript classes and they have a more traditional syntax. Using the class components provides you with a way to handle complex logic. In earlier times, the class components were the primary means to build components in React. Above all, class components are more sophisticated in comparison to the functional components.

Conclusion

Great data flow is guaranteed by React JS, which also makes it possible to create scalable and effective online application solutions. React JS guarantees that data moves from the root component to the child components in a unidirectional manner. Moreover, the program may be scaled more easily due to the unidirectional data flow, which guarantees predictability. In conclusion, it makes the codebase easier to read and guarantees browser compatibility.
