Master Advanced React

• 1. Components and Props

  function Card({ title, children }) {
      return (
          
  
              
  {title}
              
  {children}
          
      )
  }
  

  Components enable reusable UI elements. This Card component accepts title and children props.

• 2. State and Lifecycle

  import { useState, useEffect } from 'react';
  
  function Counter() {
      const [count, setCount] = useState(0);
      
      useEffect(() => {
          document.title = `You clicked ${count} times`;
      }, [count]);
  
      return (
          
  
              
  You clicked {count} times
               setCount(count + 1)}>
                  Click me
              
          
      );
  }
  

  State management allows us to handle dynamic data. Use useEffect for lifecycle hooks.
