Input Explanation
Supports CommonMark Markdown: # headings, **bold**, *italic*, - lists, ```code blocks```, [links](URL), | tables.
Calculation Basis
It parses Markdown text with a parser such as marked.js into a safe HTML tag tree and renders it on screen immediately.

- Learn the syntax - Type Markdown syntax and learn how it looks right away.
Examples
- # Heading then **bold** and *italic* render instantly
- ```js\nconsole.log("Hello")\n``` writes a code block
Cautions
- HTML tags you type are escaped for security and shown as literal tags.
- Rendering may differ slightly from a specific platform's Markdown flavor.
