That 🙈🙊🙉 feeling when you have spent hours optimizing and perfecting a pain in the a** part of the codebase, only for the reviewers to leave coments like:

"Hmmm, I understand nothing. But i trust you know better. Approved!"

"I believe the chain of multiple if/else if was easier to understand. Request changes"

"Since when does X programming language support all those? wow a whole new world"
