Text Formatting

*italic* or _italic_
**bold** or __bold__
***bold italic*** or ___bold italic___
~~strikethrough~~

Use `backticks` for inline code like `const x = 1`

Lists

- Item one
- Item two
  - Nested item
  - Another nested item
- Item three

* Alternative marker
+ Also works

1. First item
2. Second item
   1. Nested numbered
   2. Another nested
3. Third item

- [x] Completed task
- [ ] Incomplete task
- [ ] Another task

[Link text][reference-id]

[reference-id]: https://example.com "Optional title"

<https://example.com>
<email@example.com>

Anchor IDs are auto-generated from headings:

![Alt text](image.png "Optional title")

![Alt text][image-id]

[image-id]: path/to/image.png "Optional title"

[![Alt text](image.png)](https://example.com)

```javascript
function hello() {
  console.log("Hello, World!");
}
```

    // Four spaces or one tab
    function example() {
      return true;
    }
