It is an amazing way to discover how a codebase works. You pick a point of interest, and then you get the entire path from the beginning of the app's execution to that point as your stack trace, and every variable along the way too. Watches are great too for tracking a value changing over time.

Micro-services and Docker also took debugging many steps backwards - one advantage of a monolith is that you can easily step-through the entire execution, whereas if you have to cross process-boundaries it becomes a lot more complex to properly debug.

I'm working on a monorepo template at the moment where everything is debuggable with a single-click. This includes debugging native addons in C++ and Rust for Node.js projects. It's not easy - which is why people avoid debuggers so much.

I recently setup debugging in a Rust project for IntelliJ was the alternative was adding `dbg()!` statements which involved 10s recomplilation. The difficulty was implementing the right pretty-printers in lldb so you could see the value of various types because support is quite immature at the moment.
