Frontend Developer

Master variables (let, const), data types, operators, control flow (if/else, switch, loops), functions (declarations, expressions, arrow functions), scope, hoisting, and an introduction to ES6+ features like template literals, destructuring, and spread/rest operators.

Learn to select, create, modify, and remove DOM elements. Understand event listeners, event propagation (bubbling/capturing), event delegation, and common browser events to create interactive UIs.

Understand asynchronous patterns like callbacks, Promises (chaining, `Promise.all`), and Async/Await. Learn to fetch data from RESTful APIs using the Fetch API, and work with JSON data formats.

Explore ES Modules (import/export syntax) for organizing code. Understand prototypal inheritance and ES6 classes for object-oriented programming in JavaScript.

Build a single-page application that fetches real-time weather data using the OpenWeatherMap API and allows users to manage a to-do list, persisting data locally (e.g., using localStorage). Focus on dynamic DOM updates and asynchronous operations.

Learn essential Git commands (init, clone, add, commit, push, pull, status, log). Understand branching, merging, resolving conflicts, and collaborating using GitHub (forking, pull requests, issues).

Understand the role of Node.js package managers. Learn to use npm/Yarn to initialize projects, install, update, and uninstall packages. Manage dependencies (package.json, package-lock.json/yarn.lock) and define scripts.

Initialize a new project, set up Git, create a `.gitignore`, add essential development dependencies using npm/Yarn (e.g., a simple dev server), and push your work to a GitHub repository following a basic branching strategy.

Understand the concept of a UI library, React's component-based architecture, the Virtual DOM, and JSX syntax. Learn to create functional components, props for data passing, and component composition.

Master `useState` for local component state, `useEffect` for side effects (data fetching, subscriptions, DOM manipulation) with proper cleanup. Introduce `useContext` for simpler global state management.

Implement client-side routing using React Router DOM (BrowserRouter, Routes, Route, useNavigate, useParams). Handle forms with controlled components and basic client-side validation.

Explore various styling methods in React: CSS Modules, Styled Components, Emotion, and utility-first CSS frameworks like Tailwind CSS. Understand their pros and cons.

Learn about the need for global state management. Implement Redux Toolkit for complex applications: store setup, reducers, actions, and interacting with the store using `useSelector` and `useDispatch`.

Optimize React application performance using `React.memo`, `useCallback`, and `useMemo`. Learn to create reusable logic with custom hooks and implement error boundaries.

Build a React application that integrates with The Movie Database (TMDB) API. Features include searching movies, viewing movie details, routing between pages, infinite scrolling for results, and global state management (e.g., with Redux Toolkit) for favorites or user preferences.

Understand why module bundlers are crucial for modern frontend development. Learn the basics of Webpack or Vite for bundling assets, and Babel for transpiling modern JavaScript to older versions for browser compatibility.

Set up ESLint for identifying and reporting on patterns in JavaScript code to maintain code quality. Integrate Prettier for automatic code formatting to ensure consistent style across a team.

Learn techniques to improve web performance: image optimization, lazy loading, code splitting, asset compression. Understand and optimize for Core Web Vitals (LCP, FID, CLS) to enhance user experience and SEO.

Deploy frontend applications using platforms like Netlify, Vercel, or GitHub Pages. Understand basic Continuous Integration/Continuous Deployment (CI/CD) pipelines for automated builds and deployments.

Introduce testing methodologies for frontend applications. Learn to write unit tests for React components using Jest and simulate user interactions with React Testing Library.

Refine a product listing/detail page, integrating performance optimizations (lazy loading images/components), ensuring accessibility, setting up linting/formatting, and implementing basic unit tests. Deploy the application to a cloud provider like Vercel or Netlify.

Understand the benefits of static typing. Learn basic TypeScript syntax, types, interfaces, and how to integrate TypeScript into React projects for better code quality and maintainability.

Explore Next.js for building production-grade React applications. Learn about file-based routing, server-side rendering (SSR), static site generation (SSG), Incremental Static Regeneration (ISR), and API routes.

Understand the core principles of PWAs. Learn to implement service workers for offline capabilities, web app manifest, and push notifications to deliver an app-like experience on the web.

Learn to leverage popular UI component libraries like Material-UI, Ant Design, or Chakra UI to accelerate development and ensure design consistency. Understand the concept of design systems.

Gain a basic understanding of common frontend security vulnerabilities such as Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF), and CORS policies. Learn best practices for secure coding.

Develop a server-rendered or statically generated blog/e-commerce application using Next.js and TypeScript. Integrate a headless CMS (e.g., Strapi, Contentful) or a simple backend API. Focus on data fetching strategies, SEO, and type safety.
