Welcome to markdown++

✨ Key Features

Live Preview with GitHub styling
Smart Import/Export (MD, HTML, PDF)
Mermaid Diagrams for visual documentation
LaTeX Math Support for scientific notation
Emoji Support 😄 👍 🎉

💻 Code with Syntax Highlighting

  function renderMarkdown() {
    const markdown = markdownEditor.value;
    const html = marked.parse(markdown);
    const sanitizedHtml = DOMPurify.sanitize(html);
    markdownPreview.innerHTML = sanitizedHtml;
    
    // Syntax highlighting is handled automatically
    // during the parsing phase by the marked renderer.
    // Themes are applied instantly via CSS variables.
  }

🧮 Mathematical Expressions

Write complex formulas with LaTeX syntax:

Inline equation: $$E = mc^2$$

Display equations: $$\frac{\partial f}{\partial x} = \lim_{h \to 0} \frac{f(x+h) - f(x)}{h}$$

$$\sum_{i=1}^{n} i^2 = \frac{n(n+1)(2n+1)}{6}$$

📊 Mermaid Diagrams

Create powerful visualizations directly in markdown:

flowchart LR
    A[Start] --> B{Is it working?}
    B -->|Yes| C[Great!]
    B -->|No| D[Debug]
    C --> E[Deploy]
    D --> B
