Until you go to prod, you can believe a lot of things about the state of your code. Reviewing code is not merely about “Does this things work”. Testing and linting do cover most of that. Reviewing is mostly about: Will this design cover the current set of constraints (some may be conformance) and can it evolve? Are the assumptions correct? Is the security layer good enough?…

The user interface part of the code is only one single component out of many.
