Major improvements to JavaScript engine integration: - Fixed script concatenation: JavaScript now executes as complete scripts instead of line-by-line, resolving syntax errors with multi-line constructs - Enhanced document.write() integration: Content now injects directly into HTML parsing buffer and displays in browser instead of stderr only - Added comprehensive DOM element methods: All elements now have addEventListener, removeEventListener, and appendChild methods - Implemented document.body fallback: Created functional document.body object when DOM body element not available - Fixed HTML body element creation: Added proper DOM body element creation during HTML_BODY tag processing - Improved HTML environment context passing: JavaScript execution now receives HTML parsing context for proper content injection - Resolved all major JavaScript errors: Fixed "unexpected end of string", "expecting semicolon", "not a function", and "appendChild undefined" errors JavaScript integration is now fully functional with error-free execution of complex scripts including DOM manipulation, event listeners, form handling, and dynamic content generation. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
