Markdown Editor Formula / How It Works

This tool compiles Markdown elements into valid HTML on the fly. It utilizes the marked parser configured for GitHub Flavored Markdown, and routes the HTML through DOMPurify to sanitise output and eliminate security issues.

Formula:Parses markdown using marked@9 and sanitizes the output HTML using DOMPurify to prevent XSS vulnerability.
Example Calculation:

For example, typing '# Hello' produces the HTML '<h1>Hello</h1>', styled automatically inside the dark theme output container.
