### 6. Prevention Checklist
**HTML Manipulation**
- Never use innerHTML with user input
- Prefer textContent for text content
- Sanitize with DOMPurify before rendering HTML
- Avoid document.write entirely
**URL Handling**
- Validate all URLs before assignment
- Block javascript: and data: protocols
- Use URL constructor for validation
- Sanitize href attributes
**Event Handlers**
- Use addEventListener instead of inline handlers
- Sanitize all event handler input
- Avoid string-to-code patterns
**Framework-Specific**
- React: Sanitize before using unsafe APIs
- Vue: Prefer v-text over v-html
- Angular: Use built-in sanitization
