To create a demo project with a todo list using React.js, you can follow these steps: 1. Project setup: First, you need to set up a new React project using a tool like `create-react-app`: ```bash npx create-react-app todo-list-demo cd todo-list-demo ``` This will create a new React project with a default structure and install all necessary dependencies. You can then start the development server by running `npm start`. 2. Creating the Todo List component: Inside the `src` folder, create a new folder called `components` and inside it, create a new file called `TodoList.js`. This file will contain the main Todo List component. ```javascript import React, { useState } from 'react'; const TodoList = () => { const [todos, setTodos] = useState([]); const [input, setInput] = useState(''); const addTodo = (event) => { event.preventDefault(); setTodos([...todos, input]); setInput(''); }; return ( <div> <h1>Todo List</h1> <form onSubmit={addTodo}> <input type="text" value={input} onChange={(e) => setInput(e.target.value)} placeholder="Add a todo..." /> <button type="submit">Add</button> </form> <ul> {todos.map((todo, index) => ( <li key={index}>{todo}</li> ))} </ul> </div> ); }; export default TodoList; ``` In this component, we use the `useState` hook to manage the state of our todo list (`todos`) and the input field (`input`). We also define an `addTodo` function that adds a new todo item to the list when the form is submitted. 3. Including the Todo List component in the main App component: Now, open the `src/App.js` file and update it to include the `TodoList` component: ```javascript import React from 'react'; import TodoList from './components/TodoList'; function App() { return ( <div className="App"> <header className="App-header"> <TodoList /> </header> </div> ); } export default App; ``` 4. Styling the Todo List component: To style the Todo List component, you can add a new file called `TodoList.css` inside the `src/components` folder and include the styles you want. Then, import the CSS file in the `TodoList.js` file by adding `import './TodoList.css';` at the top of the file. 5. Running the demo project: Now that your demo project is set up, you can run it by executing `npm start` in the terminal. This will start the development server, and you can view your todo list application in your web browser at `http://localhost:3000`. That's it! You now have a simple demo project that uses React.js to create a todo list application. You can further enhance this project by adding features like deleting todos, editing todos, and marking todos as complete.
