FAQs on React JS In Urdu ~ JSX and React CLI (part 7 of 9) Video Lecture - Learn React JS: Fundamentals for Front-End Developers (in Urdu) - Front-End Programming
| 1. JSX is mentioned in the article. What is JSX and how does it relate to React JS? |  |
Ans. JSX stands for JavaScript XML and it is an extension to the JavaScript language. It allows us to write HTML-like syntax in our JavaScript code. JSX is used in React JS to define the structure and layout of components. It helps in combining HTML and JavaScript code together, making it easier to write and understand the code.
| 2. What is the React CLI mentioned in the article? | |
Ans. React CLI (Command Line Interface) is a tool used for creating, building, and managing React JS applications. It provides a set of commands that streamline the development process. With React CLI, developers can easily scaffold a new React project, generate components, run development servers, and build optimized production-ready bundles.
| 3. How can I install React CLI in my system? | |
Ans. To install React CLI, you need to have Node.js installed on your system. Once you have Node.js, open your terminal or command prompt and run the following command:
```
npm install -g create-react-app
```
This command will install the create-react-app package globally on your system, which includes React CLI. After the installation is complete, you can use the `create-react-app` command to create new React projects.
| 4. Can I use React CLI to add additional packages or libraries to my React project? | |
Ans. Yes, React CLI allows you to easily add additional packages or libraries to your React project. Once you have created a React project using React CLI, navigate to the project's directory using the terminal or command prompt. Then, use the following command to add a package or library:
```
npm install package-name
```
Replace `package-name` with the name of the package or library you want to add. React CLI will automatically handle the installation and dependency management for you.
| 5. Is it necessary to use React CLI for developing React JS applications? | |
Ans. No, it is not necessary to use React CLI for developing React JS applications. React CLI provides a convenient way to set up and manage React projects, especially for beginners. However, if you prefer to set up your own custom development environment or use other build tools like webpack or Parcel, you can still develop React JS applications without using React CLI. React CLI is just a tool that simplifies the development process, but it is not a requirement for using React JS.
