function parseMarkdown(markdownText) {
  // Replace headers (e.g., # Header) with <h1>, <h2>, ..., <h6> tags
  markdownText = markdownText.replace(/###### (.+)/g, '<h6>$1</h6>')
                             .replace(/##### (.+)/g, '<h5>$1</h5>')
                             .replace(/#### (.+)/g, '<h4>$1</h4>')
                             .replace(/### (.+)/g, '<h3>$1</h3>')
                             .replace(/## (.+)/g, '<h2>$1</h2>')
                             .replace(/# (.+)/g, '<h1>$1</h1>');

  // Replace bold and italic formatting
  markdownText = markdownText.replace(/\*\*(.*?)\*\*/g, '<strong>$1</strong>')
                             .replace(/\*(.*?)\*/g, '<em>$1</em>');

  // Replace unordered lists
  markdownText = markdownText.replace(/\n\* (.+)/g, '<li>$1</li>');
  markdownText = '<ul>' + markdownText + '</ul>';

  return markdownText;
}

const inputMarkdown = `
# Hello, Markdown Parser!

This is **bold** and *italic* text.

## Lists
* Item 1
* Item 2
* Item 3
`;

const parsedHTML = parseMarkdown(inputMarkdown);
console.log(parsedHTML);
