Master React from beginner to advanced with our comprehensive tutorials covering components, hooks, state management, and real-world projects.
React is a powerful JavaScript library for building dynamic, high-performance user interfaces. In this beginner-friendly guide, you'll learn what React is, why it was created, and how it revolutionized frontend development with component-based architecture and virtual DOM optimization.
Installing React is your first step toward building scalable web apps. This tutorial covers how to install React using both create-react-app and Vite, explaining the tools like Node.js and npm required to get started in modern frontend development.
Modern React development relies heavily on ES6+ JavaScript syntax. In this guide, we compare ES5 and ES6 styles in React components, helping you write cleaner, more maintainable code using arrow functions, destructuring, template literals, and more.
JSX is the syntax that allows HTML and JavaScript to live together in React. This article demystifies JSX, showing how it improves component readability and how to embed expressions, apply styles, handle lists, and use fragments for cleaner UI code.
Learn how React renders components using a virtual DOM to update only what’s needed. This guide explains React’s rendering process, how snapshots are created, and how React efficiently synchronizes UI changes with DOM elements.
React lets you show or hide parts of the UI based on conditions. In this article, you’ll explore how to use if, ternary, and logical && operators for conditional rendering — just like setting rules for dynamic UI behavior.
The virtual DOM is a key performance feature in React. This tutorial breaks down how it differs from the real DOM, how it optimizes rendering, and how React uses diffing and reconciliation to make apps faster and more efficient,
Components are the heart of every React app. This guide explains how to create reusable, maintainable components, and why breaking your UI into modular parts improves both development speed and scalability.
Should you use a functional or class component in React? This comparison guide breaks down their syntax, features, and lifecycle usage, helping you decide which type fits your project needs — especially with modern React hooks.
Composition allows you to build complex UIs from simple React components. In this article, you’ll learn how to nest, reuse, and structure components using best practices for readable and scalable applications.
In React, composition is preferred over inheritance — but why? This guide compares the two approaches, illustrating with examples how composition keeps your components clean, testable, and easier to maintain.
Props in React allow you to pass data from one component to another. This article breaks down how props work, how to destructure them, and how to simplify communication across components without relying on state.
State gives your React components memory — letting them track changes over time. In this tutorial, you’ll learn how to use useState to manage internal data and respond to user interactions in real time.
Props and state are both used for handling data in React, but they serve different purposes. This guide explains their differences, use cases, and how to choose between them for clean, reliable component logic.
Both refs and state are ways to store data in React, but they behave differently. This comparison explains when to use state (for UI) vs. when to use refs (for DOM access or hidden data), with clear real-world examples.
React prefers declarative UI, but sometimes you need to directly control DOM elements. This guide shows how to use refs to focus inputs, scroll to sections, play videos, and handle other imperative actions safely.
React’s synthetic event system makes handling user interactions easy and consistent across browsers. This tutorial covers onClick, onChange, onSubmit, and other key events — plus how to create reusable event handlers.
The onClick event in React lets you handle button presses and user clicks without reloading the page. Learn how to use it effectively to trigger actions, update state, and manage interactivity in your components.
The onChange event tracks input value changes in real time. This guide shows how to use onChange in form inputs, controlled components, and search fields to keep your UI in sync with user input.
React’s onSubmit event helps you handle form submissions without refreshing the page. In this tutorial, learn how to build forms that validate input, manage state, and send data to backends efficiently.
The onKeyDown event in React detects when users press keys, making it ideal for implementing shortcuts, navigation, or game controls. Learn how to handle key events safely and responsively in your app.
Use the onKeyUp event in React to detect when users release keys. Perfect for search inputs, form submit-on-enter logic, or accessibility features — this guide explains how to implement keyboard interaction cleanly.
The onMouseEnter event lets your app react when a user hovers over an element. In this guide, you’ll learn how to use it to trigger tooltips, animations, and hover-based UI effects without performance lag.
React Router is the standard for navigation in React apps. Learn how to set up multiple routes, use BrowserRouter, HashRouter, and MemoryRouter, and enable SPA navigation without full page reloads
React.memo helps you avoid unnecessary re-renders by memoizing components. In this tutorial, you’ll learn how it works, when to use it, and how it improves performance in large React applications.
As your React app grows, managing state across components becomes crucial. This guide explains local vs global state, tools like Context and Redux, and how to structure your state management strategy.
Hooks are special functions that let you use React features like state and effects inside functional components — replacing class lifecycles with clean, modern logic.
useState adds memory to your component — letting it store and update data that triggers a re-render when changed.
useEffect lets you perform side effects in React — like fetching data, setting up listeners, or updating the DOM after render.
useRef stores values that persist across renders without triggering re-renders — often used to access DOM elements or store silent variables.
useReducer is like useState with more control — letting you manage complex or grouped state updates through a reducer function.
useCallback memoizes a function so it doesn’t get recreated on every render — helping you optimize performance and prevent re-renders.
useEffectEvent in React 19.2 solves the stale-closure and re-render issue inside useEffect. It lets you create a stable event function that always reads the latest state without re-triggering the effect
useMemo lets you memoize expensive calculations so they only re-run when needed — perfect for derived state or heavy logic.
useContext gives components access to shared global data — like themes, auth, or user info — without prop drilling
Custom hooks let you extract and reuse logic across components — cleanly separating behavior and keeping your code DRY
Understanding the lifecycle of useEffect is key to writing reliable React code. This article walks through when effects run, how cleanups work, and how dependencies control the reactivity of your components.
React hooks are powerful, but you need to use them right — here’s a list of best practices to write clean, scalable hook-based logic.
Tailwind CSS is a utility-first framework that makes styling in React super fast, responsive, and readable — no custom CSS files needed.
