The most subtle bugs aren't in the code you write - they're in the code you approve without enough context.

This is a short story about a seemingly harmless line in a PR that I reviewed - and how it taught me to slow down, even with small changes.

The line of code below,

if(!user.isVerified) return;

intention behind this was good not to allow unverified users to proceed into the app.

But this return statement wasn't part of larger flow. It was inside a route guard - and it exited silently, without a redirect, message or error.
