  "summary": "Debugging Node.js applications can be challenging, especially when dealing with async stacks, variables changing between logs and crashes, or sporadic misbehaviors. The recommended approach is to start by using the built-in inspector with `node --inspect app.js` and then open Chrome's `chrome://inspect` to connect. For processes that are difficult to restart, such as workers or Docker containers, use `--inspect-brk` to pause on the first line or send `SIGUSR1` to a running process to enable the inspector. Breakpoints should be set conditionally rather than on every iteration, and `debugger;` statements can be used temporarily in production code. It's also important to log objects properly, such as using `console.log(JSON.stringify(user, null, 2))` or `console.dir(user, { depth: null })`. For async issues, enable `--async-stack-traces` to see the full causal chain of errors. Finally, if an application is slow rather than broken, use the built-in profiler with `node --cpu-prof` or `--heap-prof` to identify bottlenecks in CPU usage or memory allocations, respectively.",
