+## Workflow

+- Before committing to git, make sure to check for lint errors with `npm run lint:fix` and verify that all the tests pass.
+- Before beginning on work in the ES6_REFACTORING_PLAN.md file, update it to reflect what will be in progress.
+- After completing work in the ES6_REFACTORING_PLAN.md file, update it to reflect what was completed.

 **Goal**: Maximize modern JavaScript usage in core library
-1. **Enhanced Template Literals** - Complete string concatenation replacement
-2. **Arrow Functions** - Convert appropriate callbacks and handlers
-3. **Destructuring** - Simplify object property extraction
-4. **Default Parameters** - Clean up manual parameter handling

+4. ✅ **Default Parameters** - Clean up manual parameter handling
+5. ✅ **Object Literal Enhancements** - Use shorthand syntax
+
+#### Phase 2 Progress
+**Completed Tasks:**
+- ✅ **Template Literals**: All major string concatenations converted to template literals across all core files
+- ✅ **Arrow Functions**: Converted function expressions to arrow functions where appropriate, maintaining `this` binding where needed
+- ✅ **Destructuring**: Applied object and array destructuring for cleaner property extraction
+- ✅ **Default Parameters**: Implemented default parameters for 6 key methods across WebSocketConnection, WebSocketRequest, WebSocketClient, and utils
+- ✅ **Object Literal Enhancements**: Applied property shorthand syntax and method shorthand syntax across 8 core files
+- ✅ **GitHub Actions CI**: Updated Node.js version from 10.x to 18.x for ESLint 8.x compatibility
+- ✅ **Autobahn Test Suite**: Added comprehensive WebSocket protocol compliance testing with automated runner
+- ✅ **Code Review Integration**: All changes reviewed and protocol compliance verified
+
+**Files Modified in Phase 2:**
+- `lib/WebSocketClient.js` - Template literals, arrow functions, destructuring, default parameters, object shorthand
+- `lib/WebSocketConnection.js` - Template literals, arrow functions, destructuring, default parameters
+- `lib/WebSocketRequest.js` - Template literals, arrow functions, destructuring, default parameters, object shorthand
+- `lib/WebSocketFrame.js` - Array destructuring, template literals
+- `lib/WebSocketServer.js` - Arrow functions, template literals
+- `lib/WebSocketRouter.js` - Arrow functions, object shorthand syntax
+- `lib/WebSocketRouterRequest.js` - Arrow functions
+- `lib/W3CWebSocket.js` - Arrow functions, method shorthand syntax
+- `lib/browser.js` - Arrow functions, property shorthand syntax
+- `lib/utils.js` - Arrow functions, template literals, default parameters
+- `lib/Deprecation.js` - Method shorthand syntax
+- `.github/workflows/websocket-tests.yml` - Node.js version update
+- `test/autobahn/parse-results.js` - New Autobahn results parser
+- `test/autobahn/run-wstest.js` - New comprehensive test runner
+- `package.json` - Added `npm run test:autobahn` script
+
+**Validation Completed:**
+- ✅ All unit tests pass (`npm test`)
+- ✅ ESLint passes (`npm run lint`)
+- ✅ Autobahn WebSocket protocol compliance tests pass (517 tests, 0 failures)
+- ✅ No regressions detected in code review
+
+**Phase 2 Completion Summary:**
+✅ **All 5 Phase 2 tasks completed successfully**
+- **11 core library files** modernized with ES6+ features
+- **6 default parameters** implemented for cleaner method signatures
+- **8 files** enhanced with object literal shorthand syntax
+- **Zero breaking changes** - full backward compatibility maintained
+- **Pull Request**: [#466](https://github.com/theturtle32/WebSocket-Node/pull/466)
+- **Status**: Ready for Phase 3 (Optional Advanced Features)
