Question 1: Building a Responsive Navigation Bar

Problem Statement:

You've been tasked with creating a responsive navigation bar for a website. The navigation bar should adapt to various screen sizes, providing an intuitive user experience across devices. Implement the navigation bar using HTML, CSS, and JavaScript.

Solution:

HTML Structure:

```html
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Responsive Navigation Bar</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <nav class="navbar">
        <div class="menu-icon">
            <span class="bar"></span>
            <span class="bar"></span>
            <span class="bar"></span>
        </div>
        <ul class="nav-links">
            <li><a href="#">Home</a></li>
            <li><a href="#">About</a></li>
            <li><a href="#">Services</a></li>
            <li><a href="#">Contact</a></li>
        </ul>
    </nav>
    <script src="script.js"></script>
</body>
</html>
```

CSS Styling (styles.css):

```css
body {
    font-family: Arial, sans-serif;
    margin: 0;
    padding: 0;
}

.navbar {
    background-color: #333;
    color: #fff;
    display: flex;
    justify-content: space-between;
    align-items: center;
    padding: 20px;
}

.menu-icon {
    display: none;
    flex-direction: column;
    cursor: pointer;
}

.bar {
    width: 25px;
    height: 3px;
    background-color: #fff;
    margin: 3px 0;
}

.nav-links {
    display: flex;
    list-style: none;
}

.nav-links li {
    margin-right: 20px;
}

.nav-links a {
    color: #fff;
    text-decoration: none;
}

@media screen and (max-width: 768px) {
    .menu-icon {
        display: flex;
    }

    .nav-links {
        display: none;
        width: 100%;
        flex-direction: column;
        text-align: center;
        position: absolute;
        top: 70px;
        background-color: #333;
    }

    .nav-links li {
        margin-right: 0;
        margin-bottom: 15px;
    }

    .nav-links a {
        padding: 10px;
    }

    .active {
        display: block;
    }
}
```

JavaScript (script.js):

```javascript
const menuIcon = document.querySelector('.menu-icon');
const navLinks = document.querySelector('.nav-links');

menuIcon.addEventListener('click', () => {
    navLinks.classList.toggle('active');
});
```

Explanation:

This solution employs HTML, CSS, and JavaScript to create a responsive navigation bar. The HTML structure defines the layout of the navigation bar, while CSS is used for styling, including responsiveness using media queries. JavaScript adds interactivity by toggling the visibility of the navigation links when the menu icon is clicked.

Question 2: Implementing a CRUD Application with React.js

Problem Statement:

Develop a CRUD (Create, Read, Update, Delete) application using React.js. The application should allow users to perform basic CRUD operations on a list of items. Ensure proper state management and user interface design.

Solution:

```javascript
// App.js
import React, { useState } from 'react';
import './App.css';

function App() {
  const [items, setItems] = useState([]);
  const [inputValue, setInputValue] = useState('');

  const handleInputChange = (e) => {
    setInputValue(e.target.value);
  };

  const handleAddItem = () => {
    if (inputValue.trim() !== '') {
      setItems([...items, { id: Date.now(), name: inputValue }]);
      setInputValue('');
    }
  };

  const handleDeleteItem = (id) => {
    setItems(items.filter(item => item.id !== id));
  };

  return (
    <div className="App">
      <h1>CRUD Application</h1>
      <input
        type="text"
        value={inputValue}
        onChange={handleInputChange}
        placeholder="Enter item name"
      />
      <button onClick={handleAddItem}>Add Item</button>
      <ul>
        {items.map(item => (
          <li key={item.id}>
            {item.name}
            <button onClick={() => handleDeleteItem(item.id)}>Delete</button>
          </li>
        ))}
      </ul>
    </div>
  );
}

export default App;
```

Explanation:

This React.js application allows users to perform CRUD operations on a list of items. State is managed using the useState hook, with items stored in an array. Users can add new items, which are appended to the list with a unique identifier generated using the current timestamp. Items can also be deleted by filtering the array based on the item's ID.
