If you are reviewing a PR and it's not two lines of code, if you want to create value for your team: 1. Check out the branch on your local. 2. Review the new code without checking what exactly was changed. This enables completely different mental faculties.

Due to some projects at work written in go, I started learning it. It's a very nice and cool language. I do get tremendous satisfaction writing go. I don't renounce, node and rust, but just adding go, to my repertoire.
