Todo App
- CRUD operations
- State & hooks mastery
- Local storage
Before diving into React, make sure you are comfortable with the foundational web technologies below.
These JavaScript concepts are essential before moving into React. Mastering them will make React feel intuitive instead of confusing.
Understand how functions retain access to variables from their outer scope, even after execution.

Learn how execution context works and how this behaves
in functions, objects, and arrow functions.
Handle asynchronous operations cleanly using promises and modern async/await syntax.
Work efficiently with data using
map, filter, and reduce.
Structure your code using import and
export for scalable applications.
Learn the core ideas that make React powerful. These concepts form the foundation of every modern React application.
React is a JavaScript library for building fast, interactive user interfaces using a component-based architecture.
JSX lets you write UI code that looks like HTML inside JavaScript, making components easy to read and maintain.
Components are reusable pieces of UI written as JavaScript functions that return JSX.
Props allow data to flow from parent to child components, making UIs dynamic and reusable.
State is used to store and manage data that changes over time and triggers UI updates.
Handle clicks, input changes, and form submissions using React’s synthetic event system.
Render different UI elements based on conditions using JavaScript logic.
Render collections of data efficiently while helping React track changes using unique keys.
Hooks let you use state, lifecycle features, and powerful optimizations without writing class components. This is where React truly shines.
Manage local component state and trigger UI updates when data changes.
Handle side effects like data fetching, subscriptions, and DOM updates.
Access global state and avoid prop drilling across deeply nested components.
Persist values between renders and directly interact with DOM elements.
Optimize expensive calculations by memoizing computed values.
Prevent unnecessary re-renders by memoizing function references.
Extract reusable logic into custom hooks to keep components clean and maintainable.
React offers multiple ways to style your application — from traditional CSS to utility-first frameworks and full-featured UI libraries.
Use global styles or preprocessors like SCSS for variables, nesting, and reusable mixins.
Scope styles locally to components and avoid class name collisions.
Write CSS directly inside JavaScript using component-based styling.
Utility-first CSS framework for building modern UIs rapidly.
Google’s Material Design components with powerful theming support.
Enterprise-grade UI components for large-scale applications.
Accessible, composable components with style props built in.
Routing enables navigation between pages without reloading the browser. React Router is the standard solution for handling routes in React apps.
A powerful routing library that allows you to map URLs to components and create single-page applications.
Wraps your app and enables clean URLs using the HTML5 history API.
Define which component should render for a given path using declarative route definitions.
Capture dynamic values from the URL to build detail pages and dynamic views.
Create layouts with child routes that share UI and structure.
Restrict access to routes based on authentication or user roles.
Fetching and managing external data is core to real-world React apps. This step focuses on APIs, async handling, and modern data caching tools.
Native browser API for making HTTP requests using promises.
Promise-based HTTP client with interceptors, auto JSON parsing, and better error handling.
Communicate with backend services using RESTful endpoints and HTTP methods.
Gracefully handle failures, network issues, and API errors.
Improve UX using spinners, skeletons, and optimistic UI updates.
Powerful server-state management with caching, background updates, retries, and pagination.
Lightweight data fetching with built-in caching and revalidation.
Advanced patterns and concepts that help you build scalable, reusable, and resilient React applications.
Build flexible, shared-state components with an intuitive API.
Share logic between components using functions as children.
Render components outside the DOM hierarchy for modals and overlays.
Catch JavaScript errors in UI trees and display graceful fallbacks.
Enhance components by wrapping them with reusable logic.
Learn how React renders components on the server for performance gains.
These projects transform React knowledge into real-world, production-ready experience.
