React Career Roadmap: Frontend Developer Roadmap

Build a Simple React To-Do App

Create a React app that allows users to add, delete, and mark tasks as completed.

Expected output: A functional to-do list with add, delete, and toggle complete features.

Hint: Use useState for managing the list of tasks and map to render them.

Implement React Router

Add routing to your React app with at least two pages: Home and About.

Expected output: A multi-page React app with navigation links.

Hint: Use react-router-dom's BrowserRouter, Route, and Link components.

React hooks are functions like useState and useEffect that let you use state and lifecycle features in functional components, making code cleaner and more reusable.

React uses a virtual DOM to efficiently update the UI by only re-rendering components that change, unlike manual DOM manipulation which can be slower and error-prone.

Keys help React identify which items have changed, been added, or removed, improving rendering performance and avoiding UI bugs.
