Examples

// Example: Bubble Sort Visualization
function bubbleSort(arr) {
  const n = arr.length;
  for (let i = 0; i < n - 1; i++) {
    for (let j = 0; j < n - i - 1; j++) {
      if (arr[j] > arr[j + 1]) {
        [arr[j], arr[j + 1]] = [arr[j + 1], arr[j]];
      }
    }
  }
  return arr;
}

console.log(bubbleSort([64, 34, 25, 12, 22, 11, 90]));
// Output: [11, 12, 22, 25, 34, 64, 90]

# Example: Data Analysis with Pandas
import pandas as pd

# Load and analyze
df = pd.read_csv('sales_data.csv')

# Find trends
monthly_sales = df.groupby('month')['revenue'].sum()
top_products = df.groupby('product')['units'].sum().nlargest(5)

print(f"Total Revenue: ${df['revenue'].sum():,.2f}")
print(f"Best Month: {monthly_sales.idxmax()}")

// Example: Interactive useEffect Demo
import { useState, useEffect } from 'react';

export default function Timer() {
  const [seconds, setSeconds] = useState(0);

  useEffect(() => {
    const interval = setInterval(() => {
      setSeconds(s => s + 1);
    }, 1000);

    // Cleanup on unmount
    return () => clearInterval(interval);
  }, []);

  return <div>Seconds: {seconds}</div>;
