ByteByteGo Reference Linker

A Tampermonkey userscript that enhances ByteByteGo course pages by converting [n] reference markers into clickable links.

Features

• Clickable References: [1], [2], etc. in the text become clickable links that open the referenced URL in a new tab
• Quick Navigation: A ↓ arrow next to each reference scrolls you to the References/Resources section with a highlight effect
• Hover Tooltips: Hover over a reference to see the description
• Multiple Formats Supported: Works with various reference formats:
  • [n] Description: URL
  • n. Description URL
  • Ordered lists (<ol><li>...</li></ol>)

How It Works

1. The script scans the page for a References or Resources section (supports <h2>, <h3> headers)
2. Parses references in various formats and extracts URLs and descriptions
3. Finds all [n] markers in the main content
4. Replaces them with clickable links + navigation arrows
5. Uses a MutationObserver to handle dynamically loaded content
