Master React Development

Learn React fundamentals, state management, and modern development practices for building dynamic user interfaces.

Key React Features

Discover the core principles and capabilities that make React a popular choice for modern web development.

React Components

Create reusable UI components using functions and classes for clean, maintainable code structures.


function Button({ label, onClick }) {
  return (
    <button className="p-3 bg-blue-500 text-white rounded" onClick={onClick}>
      {label}
    </button>
  );
}

State Management

Use local component state and React hooks to manage UI state efficiently with useState and useContext.


function Counter() {
  const [count, setCount] = useState(0);
  return (
    <div>
      <button onClick={() => setCount(prev => prev + 1)}>+
    </div>
  );
}

React Hooks

Use lifecycle methods as React hooks to add advanced features like data loading and animations to functional components.


useEffect(() => {
  document.title = `You clicked ${count} times`;
}, [count]);

Why React?

React is a powerful JavaScript library that allows developers to build complex UIs with reusable components. It provides a virtual DOM for efficient rendering and supports both declarative and functional programming paradigms.

Millions of developers rely on React to build fast, interactive user interfaces for web applications.

Advanced React Patterns

Expand your React knowledge with best practices for state management, component composition, and optimization techniques.

Custom Hooks

Create reusable logic across components by building custom React hooks encapsulating specific functionality.


const useCounter = (initial = 0) => {
  const [count, setCount] = useState(initial);
  const increment = () => setCount(c => c + 1);
  const decrement = () => setCount(c => Math.max(c - 1, 0));
  return { count, increment, decrement };
}

Context API

Manage shared state across multiple components without prop drilling using the Context API.


const ThemeContext = createContext();

function App() {
  const [theme, setTheme] = useState('light');
  return ( 
    <ThemeContext.Provider value={theme}>
      <Button>Toggle Theme</Button>
    </ThemeContext.Provider>
  );
}

Performance Optimization

Optimize component renders with React.memo and use performance profiling tools to identify bottlenecks.


const MemoizedListItem = React.memo(({ item }) => {
  return (
    <div>
      {item.name}
      <p>{item.description}</p>
    </div>
  );
});
