The "let errors happen and catch them high up" approach is something I wish I'd internalized sooner. Early in my career I was wrapping literally everything in try/catch and returning null or default values all over the place. Code looked "safe" but it was lying — silently swallowing errors and producing bad state downstream.
One pattern I've found helpful is creating a thin error boundary layer at route/controller level that logs + maps errors to user-friendly responses, and then letting everything underneath just throw freely. Way cleaner than scattering catch blocks everywhere.
The narrative format works well for this topic btw. Stack unwinding is one of those things that's hard to visualize from docs alone — the "tearing down boxes" metaphor makes it click.
Kai, you're spot on. "Silently swallowing errors" is exactly the trap so many of us fall into early on. Your pattern of a thin error boundary at the route/controller level is the perfect real-world implementation of this philosophy. Thanks for adding such great senior-level context! cheers! 💯✨
