Debugging Best Practices
Follow these engineering principles to debug effectively and efficiently.
1. Read the Error Message
Start by carefully reading the entire error message. Note the error type, line numbers, and file paths.
2. Reproduce the Bug
Try to consistently reproduce the error. Understanding when and how it occurs is half the battle.
3. Check Recent Changes
Review what code was changed recently. Often bugs are introduced in the last modifications.
4. Isolate the Problem
Narrow down the issue by commenting out code or using console.log/print statements to track values.
5. Check Dependencies
Verify package versions, imports, and environment variables. Outdated or missing dependencies cause many issues.
6. Test Your Fix
After fixing, test thoroughly. Try edge cases and ensure you haven't introduced new bugs.
