| 5 | ## Debugging Methodology |
| 6 | |
| 7 | ### 1. Problem Definition |
| 8 | - Understand the expected behavior |
| 9 | - Document the actual behavior |
| 10 | - Identify when the issue started |
| 11 | - Determine reproducibility steps |
| 12 | |
| 13 | ### 2. Information Gathering |
| 14 | - Collect error messages and stack traces |
| 15 | - Review relevant logs |
| 16 | - Check recent code changes |
| 17 | - Examine system resources and environment |
| 18 | |
| 19 | ### 3. Hypothesis Formation |
| 20 | - Generate possible causes |
| 21 | - Prioritize based on likelihood |
| 22 | - Consider edge cases and race conditions |
| 23 | |
| 24 | ### 4. Systematic Testing |
| 25 | - Isolate the problem area |
| 26 | - Use binary search to narrow scope |
| 27 | - Add strategic logging/debugging statements |
| 28 | - Test hypotheses one at a time |
| 29 | |
| 30 | ### 5. Root Cause Analysis |
| 31 | - Identify the underlying issue |
| 32 | - Understand why it occurred |
| 33 | - Consider prevention strategies |
| 34 | |
| 35 | ## Debugging Techniques |
| 36 | |
| 37 | ### Code-Level Debugging |
| 38 | - Strategic breakpoint placement |
| 39 | - Variable inspection and watching |
| 40 | - Stack trace analysis |
| 41 | - Memory profiling |
| 42 | - Performance profiling |
| 43 | |
| 44 | ### System-Level Debugging |
| 45 | - Log analysis and correlation |
| 46 | - Network traffic inspection |
| 47 | - Database query analysis |
| 48 | - Resource monitoring (CPU, memory, I/O) |
| 49 | - Dependency version conflicts |
| 50 | |
| 51 | ### Common Bug Patterns |
| 52 | |
| 53 | **Logic Errors** |
| 54 | - Off-by-one errors |
| 55 | - Incorrect conditional logic |
| 56 | - State management issues |
| 57 | - Race conditions |
| 58 | |
| 59 | **Memory Issues** |
| 60 | - Memory leaks |
| 61 | - Circular references |
| 62 | - Excessive memory allocation |
| 63 | - Buffer overflows |
| 64 | |
| 65 | **Async/Concurrency** |
| 66 | - Race conditions |
| 67 | - Deadlocks |
| 68 | - Unhandled promise rejections |
| 69 | - Callback hell issues |
| 70 | |
| 71 | **Integration Issues** |
| 72 | - API contract mismatches |
| 73 | - Data format inconsistencies |
| 74 | - Authentication/authorization failures |
| 75 | - Network timeout issues |
| 76 | |
| 77 | ## Debugging Tools |
| 78 | |
| 79 | - Browser DevTools (Chrome, Firefox) |
| 80 | - Node.js debugger and inspector |
| 81 | - VS Code debugger |
| 82 | - Console logging strategies |
| 83 | - Network inspection tools |
| 84 | - Memory profilers |
| 85 | - Performance monitoring tools |
| 86 | |
| 87 | ## Best Practices |
| 88 | |
| 89 | 1. **Reproduce Consistently**: Ensure you can reliably trigger the bug |
| 90 | 2. **Minimize Test Case**: Create the smallest example that shows the issue |
| 91 | 3. **Document Findings**: Keep notes on what you've tested |
| 92 | 4. **Version Control**: Use git bisect to find when bugs were introduced |
| 93 | 5. **Test Fixes**: Verify the fix doesn't introduce new issues |
| 94 | 6. **Prevent Recurrence**: Add tests to catch similar bugs in the future |
| 95 | |
| 96 | ## Communication |
| 97 | |
| 98 | When debugging, provide: |
| 99 | - Clear problem statement |
| 100 | - Steps to reproduce |
| 101 | - Root cause explanation |
| 102 | - Proposed solution with reasoning |
| 103 | - Prevention recommendations |
