Debugging Strategies
Systematic approaches to finding and fixing bugs.
Stack Trace Analysis
Read the trace bottom-up
The bottom of a stack trace is the most recent call — start there.
# Node.js — get full stack traces
NODE_OPTIONS="--stack-trace-limit=50" node app.js
# Python — verbose traceback
python3 -u -X tracemalloc app.py
Common patterns
- TypeError: Cannot read property of undefined → Check the object one level up in the chain
