Debug a Node.js memory leak by attaching via the inspector protocol to step through code at runtime, inspect state, and capture heap snapshots to identify retained objects causing the leak.

The best way to investigate slow React rendering is to record a Chrome DevTools Performance trace, then analyze the Flame Chart and Long Tasks to identify the top JavaScript contributors blocking the main thread.

Strace helps with troubleshooting failing syscalls by tracing the library and system calls made by a process, allowing you to filter outputs and understand exactly where an OS-level failure occurs.

Yes, you can use tcpdump to capture network packet traffic and Wireshark to inspect it, allowing you to diagnose request, connection, and TLS timing to locate exactly where network failures occur.

Analyze core dumps and native crashes using lldb backtraces to inspect the call stack at the moment of failure, enabling you to triage the crash and pinpoint the root cause of the defect.

Yes, a structured workflow is required to systematically reproduce the issue, isolate variables, and validate hypotheses using tool-specific techniques to pinpoint the root cause of defects accurately.
