1. Typography & Text Styling

This paragraph contains a mix of bold, italic, bold-italic, strikethrough, inline code, and a hyperlink example.

You can also use HTML tags for underline (underlined text) and sub/superscripts (H2O, X^2^), depending on parser support. Footnotes^[1] are also a great test for advanced readers.

2. Blockquotes & Nesting

Primary blockquote layer. This tests standard quote rendering.

Nested blockquote layer. Ensuring multiple levels of indentation parse correctly.

Third-layer nesting with code inside: console.log("deep nesting");

Back to the first layer. A quote can contain lists:

• Item one in a quote
• Item two in a quote

3. List Variations

Ordered List

1. First major item
2. Second major item
   1. Sub-item A with a long description to test text wrapping behavior inside list items.
   2. Sub-item B
3. Third major item

Unordered List

• Bullet point item one
• Bullet point item two
  • Nested bullet point
    • Deeply nested bullet point
• Bullet point item three

Task List (Checklists)

• Completed task item
• Pending task item with edge-case characters: *, _, [ ]
• Another pending task item

4. Data Tables

5. Code Highlighting & Blocks

JavaScript Example

// A complex snippet to test syntax highlighting
function fibonacci(n) {
    if (n <= 1) return n;
    return fibonacci(n - 1) + fibonacci(n - 2);
}

const result = fibonacci(10);
console.log(`Result: ${result}`);

Python Example

def quicksort(arr):
    if len(arr) <= 1:
        return arr
    pivot = arr[len(arr) // 2]
    left = [x for x in arr if x < pivot]
    middle = [x for x in arr if x == pivot]
    right = [x for x in arr if x > pivot]
    return quicksort(left) + middle + quicksort(right)

6. Mathematical Expressions

Inline Math: The quadratic formula is given by $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$.
