JavaScript | MDN
JavaScript (JS) is a lightweight interpreted (or just-in-time compiled) programming language with first-class functions. While it is most well-known as the scripting language for Web pages, many non-browser environments also use it, such as Node.js, Apache CouchDB and Adobe Acrobat. JavaScript is a prototype-based, garbage-collected, dynamic language, supporting multiple paradigms such as imperative, functional, and object-oriented.

Benefits
Link cards provide several advantages over plain links:
- Visual Appeal - Rich previews are more engaging than plain text links
- Context - Users see what they're clicking before they click
- Automatic Metadata - Fetches title, description, and images automatically
- Consistent Design - Maintains visual consistency across your content
- Better UX - Hover effects and clear call-to-action improve user experience
Technical Details
The link card component:
- Fetches Open Graph and Twitter Card metadata
- Falls back to basic HTML meta tags if social metadata is unavailable
- Supports custom descriptions to override fetched content
- Includes responsive design for mobile devices
- Provides hover effects and accessibility features
- Opens links in new tabs with proper security attributes
Fallback Behavior
If metadata cannot be fetched (network errors, timeouts, or missing tags), the card displays:
- Domain name as the title
- Custom description if provided
- No image
- Still functional as a clickable link
This ensures cards always render, even when external resources are unavailable.
