What is React JS ?
React JS is a popular, open-source JavaScript library developed by Facebook for building user interfaces, specifically for single-page applications.
It allows developers to create reusable UI components, making the development process faster and more efficient.
Key Features of React JS:
- Component-Based Architecture: React divides the UI into small, reusable components, making the code more modular and easier to maintain.
- Virtual DOM: Instead of updating the real DOM directly, React uses a virtual DOM to make updates more efficient. It compares changes in the virtual DOM and updates only the necessary parts of the real DOM.
- Declarative Syntax: React uses a declarative programming approach, making the code more predictable and easier to debug.
- JSX (JavaScript XML): JSX allows developers to write HTML-like syntax within JavaScript, making the code more readable and easier to develop.
- One-Way Data Binding: React follows a unidirectional data flow, making the application more predictable and easier to debug.
- React Hooks: Hooks are functions that allow developers to use state and other React features in functional components, eliminating the need for class components in many cases.
- Strong Ecosystem: React has a rich ecosystem with tools like Redux, React Router, and libraries that enhance its functionality.
Benefits of Using React :
- Faster Rendering: Virtual DOM ensures efficient updates and rendering.
- Reusable Components: Simplifies development and reduces code duplication.
- SEO-Friendly: React can render on the server, making it more search-engine-friendly compared to other JavaScript frameworks.
- Large Community: It has an active community, meaning plenty of resources, tutorials, and libraries are available.
Application of React JS :
- Building dynamic web applications.
- Creating mobile apps using React Native.
- Developing single-page applications (SPAs).
- Building interactive dashboards and user interfaces.
How to start a new react js Project
1. Install Node.js
React requires Node.js to run. Install it if you haven’t already. Download and install Node.js from https://nodejs.org. After installation, verify it by running:
node -v
npm -v
2. Create a React App
The easiest way to start a new React project is by using Create React App (CRA), a CLI tool that sets up everything for you.
Using npx (recommended):
Open a terminal/command prompt and run:
npx create-react-app my-app
Replace my-app with your desired project name. npx will download the tool temporarily and create your project.
Using npm:
If you prefer:
npm init react-app my-app
3. Navigate to the Project Folder
cd my-app
4. Start the Development Server
Run:
npm start
Open http://localhost:3000 in your browser to see your React app running!
5. Understand the Project Structure
The default project structure looks like this:
my-app/
├── node_modules/ # Dependencies
├── public/ # Static files
├── src/ # Main code folder
│ ├── App.css # App styles
│ ├── App.js # Main App component
│ ├── index.js # Entry point
│ └── …
├── package.json # Project settings and dependencies
└── …
6. Start Coding
Open the project folder in your favorite code editor (e.g., VS Code). Edit files in the src/ folder to see live updates in the browser.
Optional: Use TypeScript (if needed)
To create a React app with TypeScript:
npx create-react-app my-app –template typescript
7. Install Additional Dependencies (Optional)
As you build your project, you might need extra libraries like:
- React Router: For routing.
npm install react-router-dom - Axios: For making API calls.
npm install axios
Once you’re set up, you can build your components and explore React’s features. Let me know if you need help with anything specific!

- Search for location: Users can input a city name and view the weather data for that location.
- Display weather info: Show the temperature, humidity, wind speed, and weather condition.
- Error handling: Show an error message if the location is invalid or if the API request fails.
- Unit conversion: Allow users to switch between Celsius and Fahrenheit.
- Responsive design: Ensure the app works well on both desktop and mobile devices.
What you will Learn :
- API integration: Fetch data from a weather API.
- DOM manipulation: Dynamically display weather data.
- Asynchronous JavaScript: Use fetch to make requests to an API and handle promises.
- Basic error handling: Handle scenarios like invalid input or API errors.
- Basic CSS: Style the application to make it visually appealing.

{
document.getElementById(“error-message”).textContent = “Please enter a city name.”;
return;
}
const apiKey = “YOUR_API_KEY”; // Get your own API key from OpenWeatherMap
const apiUrl = `https://api.openweathermap.org/data/2.5/weather?q=${city}&appid=${apiKey}&units=metric`;
fetch(apiUrl)
.then(response => response.json())
.then(data => {
if (data.cod === “404”)
{
document.getElementById(“error-message”).textContent = “City not found!”;
} else
{
document.getElementById(“error-message”).textContent = “”;
document.getElementById(“city-name”).textContent = data.name;
document.getElementById(“temperature”).textContent = `Temperature: ${data.main.temp}°C`;
document.getElementById(“humidity”).textContent = `Humidity: ${data.main.humidity}%`;
document.getElementById(“wind-speed”).textContent = `Wind Speed: ${data.wind.speed} m/s`;
document.getElementById(“weather-description”).textContent = `Condition: ${data.weather[0].description}`;
}
})
.catch(error => {
document.getElementById(“error-message”).textContent = “Error fetching data. Please try again.”;
});
});
How to Run this Project :

FAQ's (Frequently asked Questions)
React JS Projects with Source Code
React JS is an open-source JavaScript library for building user interfaces, especially single-page applications. It allows developers to create reusable UI components and manage the state of an application efficiently.
React JS is popular due to its component-based architecture, which makes it easy to reuse code. It also has a virtual DOM, which boosts performance, and offers flexibility for handling UI updates.
React is also supported by a large community and has great tools for debugging and testing.
State management refers to how the application’s data (state) is stored and updated. In React, state is managed within components. React provides hooks like useState and useReducer for managing state locally in a component. For larger applications, tools like Redux or Context API can be used to manage state globally across the app.
API calls can be made using JavaScript functions like fetch or axios. In React, API calls are typically made in lifecycle methods (like useEffect) or event handlers. For example, you can fetch data from a weather API to display weather information on the screen.
- Functional Components: These are simpler and use hooks to manage state and side effects. They are easier to test and understand.
- Class Components: Older approach, using ES6 classes to create components with state and lifecycle methods.
React now favors functional components because they offer a more concise and efficient way of handling state and effects with hooks.
Forms in React are controlled components. This means the form data is managed in the component’s state. React allows you to handle form input changes using the onChange event and then update the state accordingly. When the form is submitted, the state holds the values for processing.
You can deploy React apps to platforms like Netlify, Vercel, or GitHub Pages for free. First, you need to build the React app using npm run build, which generates static files. Then, you can upload or push those files to your hosting platform.
JSX (JavaScript XML) is a syntax extension for JavaScript that looks similar to HTML. It allows you to write HTML-like elements in JavaScript code and is later compiled into regular JavaScript. JSX makes it easier to create and understand React components by combining markup and logic in a single file.
React hooks are functions that allow you to use state and lifecycle features in functional components. Some common hooks are:
- useState: For managing state.
- useEffect: For side effects like fetching data.
- useContext: For accessing context data in functional components.
useReducer: For complex state logic.
- Build projects: Start with small projects like a to-do list or weather app and gradually increase the complexity.
- Learn about state management with tools like Redux or Context API.
- Practice writing functional components using hooks.
- Stay updated with React documentation and community resources like blogs, forums, and tutorials.
- Join coding communities, contribute to open-source projects, and seek feedback on your work.
The Virtual DOM is a lightweight copy of the actual DOM. React creates a Virtual DOM to optimize updates by comparing it with the real DOM and only applying necessary changes. This leads to better performance because it minimizes the number of direct updates to the real DOM.
React Router is a popular library for handling routing in React applications. It enables you to create different views in your application and manage navigation between them using the Route, Link, and BrowserRouter components.
Yes, React is often used with backend technologies like Node.js, Express, and MongoDB to build full-stack applications. React handles the frontend, while Node.js and Express serve as the backend, allowing you to handle API requests, interact with databases, and manage user authentication.
Lifecycle methods are specific methods in React class components that get called at different stages of a component’s life (e.g., mounting, updating, unmounting). Common lifecycle methods include:
- componentDidMount: Called after the component is mounted.
- componentDidUpdate: Called after the component updates.
- componentWillUnmount: Called before the component is removed.
In functional components, similar functionality is achieved using the useEffect hook.
You can make a React app responsive by using CSS media queries, CSS Flexbox, and CSS Grid. Additionally, frameworks like Bootstrap or Material-UI can help with responsive design components. Ensure your app adjusts its layout and content based on the screen size, providing a seamless experience across devices.
Hope you found good understanding about Most Popular State Management Libraries in React, with detailed explanations. Hope this helps you.
