FAQs on REACT JS TUTORIAL #1 - Reactjs Javascript Introduction & Workspace Setup Video Lecture - Learn React JS: Fundamentals for Front-End Developers - Front-End Programming

1. What is React JS?
Ans. React JS is a JavaScript library used for building user interfaces. It allows developers to create reusable UI components that can be rendered efficiently. React JS follows a component-based architecture and uses a virtual DOM for efficient rendering.
2. How to set up a workspace for React JS development?
Ans. To set up a workspace for React JS development, you need to have Node.js and npm (Node Package Manager) installed on your computer. Once installed, you can create a new React project using the create-react-app command. This command sets up a basic React project structure with all the necessary dependencies. After creating the project, you can navigate to its directory and start the development server using the npm start command.
3. What is the difference between React JS and React Native?
Ans. React JS and React Native are both developed by Facebook and are used for building user interfaces, but they have some key differences. React JS is a JavaScript library used for building web applications, while React Native is a framework that allows you to build native mobile applications using JavaScript. React JS uses HTML and CSS for rendering, while React Native uses native components for rendering on iOS and Android platforms.
4. What is the virtual DOM in React JS?
Ans. The virtual DOM in React JS is a lightweight copy of the actual DOM (Document Object Model) that is used for efficient rendering of components. When changes are made to the virtual DOM, React compares it with the actual DOM and updates only the necessary components, minimizing the number of DOM manipulations. This makes React JS highly efficient and fast.
5. What are the advantages of using React JS for front-end development?
Ans. Some advantages of using React JS for front-end development include: - Reusability: React allows developers to create reusable UI components, making it easier to maintain and update the code. - Efficiency: React uses a virtual DOM and efficient diffing algorithms, resulting in faster rendering and better performance. - Component-based architecture: React follows a component-based architecture, making it easier to break down the UI into smaller, manageable pieces. - Large community and ecosystem: React has a large and active community, with a vast ecosystem of libraries and tools that can enhance development productivity. - Cross-platform compatibility: React can be used to develop web applications as well as native mobile applications using React Native.
