## What it is
llnode is an LLDB plugin written in C++ for inspecting Node.js and V8 JavaScript states. It enables inspection of JavaScript stack frames, objects, and source code in live Node.js processes and core dumps.

## Use cases
- debug a hung Node.js process in LLDB
- analyze a Node.js core dump to find what JavaScript was running
- inspect JavaScript objects and stack frames during debugging
- postmortem debugging of crashed Node.js applications
- find memory leaks by examining live JavaScript heap objects

## When to choose
- you need to debug Node.js processes or core dumps at the JavaScript level
- you want to combine C/C++ LLDB debugging with JavaScript visibility
- you are doing postmortem analysis of crashed Node.js applications

## When to avoid
- you only need basic logging or APM-style monitoring rather than low-level debugging
- you use a Node.js build not from official channels (e.g. distro apt packages)
- you need a debugger for non-Node.js JavaScript runtimes
