VS Code Debugger: Inspect State Instead of Adding Prints
Repeated print statements can obscure the code and still miss the state at a failing branch. This guide gives you a small, testable way to approach the issue before changing a live system.
A practical workflow
- Set a breakpoint near the failing operation and reproduce the smallest input.
- Inspect the call stack and variables, then step through the next statements before changing code.
What to check
Debug against a local or safe test environment; pausing a live service can affect users. Compare the result with the original problem and record what changed. If a measurement or test does not support the change, revisit the assumption rather than adding more complexity.
Keep the experiment small enough to reverse. Document the starting state, the change and the result so another person can repeat the process. Product menus and versions can change, so check the current documentation for your environment.
