So within my own area of the codebase and tech stack I own, I'm very comfortable and confident leaving feedback and sharing thoughts. However, I know that in order to grow to senior, I need to expand past my immediate area into other spaces like the components and services built by other teams in my org like sister teams. For those areas, I'm unsure how to share my thoughts since I'm not an expert in those codebases. So let's say I come across a code review from one of these more "separate" areas from my own and the engineer behind the diff is more senior than me - How can I leave my feedback in a way that respects the situation?
