To build a portfolio website in React, you will need to have the React library and a code editor installed on your computer. You will also need to have a basic understanding of HTML, CSS, and JavaScript.

1. First, create a new React application using the create-react-app command-line tool.
2. Next, create the components for your portfolio website. You will need at least a header, footer, and main content area. You can also create additional components for specific sections of your website, such as an about section, a portfolio section, and a contact form.
3. Design the layout and appearance of your website using HTML and CSS. You can use a CSS framework such as Bootstrap or create your own styles.
4. Add content to your website, including text, images, and links. You can use the React state or props to pass data to your components.
5. Test your website and make any necessary adjustments.
6. Deploy your website to a hosting platform, such as GitHub Pages or Netlify.

That’s it! With these steps, you can build a professional and interactive portfolio website using React. Remember to keep your website up to date and make regular updates to showcase your skills and projects.

This code creates a basic portfolio website with a header, main content area, and footer. The header displays the name and title of the user, and the main content area includes sections for the user’s about me, skills, and projects. The footer includes a form for the user to update their name, title and skills.

In the code, the useState hook is used to create state variables for the user’s name, title, about me, skills, and projects. The useState hook returns an array with the current state value and a function for updating the state value. The component’s form fields are connected to the state variables using the value and onChange props, and the state values are displayed in the JSX template using curly braces.

The component also includes event handlers for the form fields that update the state variables when the user types in the fields. For the skills and projects fields, the state variables are arrays, so the event handlers use the split method to convert the comma-separated values into arrays.

In summary, this code creates a basic portfolio website in React that allows the user to update their name, title, about me, skills, and projects. By using the useState hook and form fields, the component can capture and update the user’s data and display it in the user interface. Whether you’re a beginner or an experienced developer, this code provides a good starting point for building a portfolio website in React.
