Create a toggle button in React JS

 import React, { useState } from 'react';

 const ToggleButton = () => {
   const [isToggled, setToggled] = useState(false);

   const handleToggle = () => {
     setToggled(!isToggled);
   };

   return (
     <div>
       <p>{isToggled ? 'Toggled ON' : 'Toggled OFF'}</p>
       <button onClick={handleToggle}>
         {isToggled ? 'Turn OFF' : 'Turn ON'}
       </button>
     </div>
   );
 };

 export default ToggleButton;

The useState hook manages the button state, and a click toggles between 'ON' and 'OFF'. The component dynamically updates the button text and displays the current state.

Create a simple profile card with name, image and title using HTML and CSS

 <div class="profile-card">
   <img src="profile-image.jpg" alt="Profile Image">
   <h2>John Doe</h2>
   <p>Web Developer</p>
 </div>

 .profile-card {
   text-align: center;
   padding: 20px;
   border: 1px solid #ccc;
   border-radius: 8px;
   box-shadow: 0 4px 8px rgba(0, 0, 0, 0.1);
 }

 .profile-card img {
   width: 100%;
   border-radius: 50%;
   margin-bottom: 10px;
 }

Create a clean profile card using HTML and CSS with a rounded image, displaying the name 'John Doe' and the title 'Web Developer'. The card features a subtle box-shadow for a modern look.

Create a counter application using React JS (functional components)

       <h2>Counter: {count}</h2>
       <button onClick={() => setCount(count + 1)}>Increment</button>
     </div>
   );
 };
