So I recently came across a huge React codebase that was hard to understand. There was no proper documentation, it wasn't clear how data is passed around and there are no automated unit tests. Now this is just the tip of the iceberg and I don't want to waste your time with a long rant. I would rather spend time discussing and coming up with solutions.

I think people write bad code (myself included) not because they are bad people but because it is easy to do so, unrealistic deadlines make it even worse. I think if it were hard to write bad code, there would be less of it around.

It is also not just a technical problem, people have to enforce it too. Have a well defined spec on how your codebase should be structured, documented and tested. Then don't approve that PR unless it passes those specs.

I could go on about this, I want to know how you feel on this topic and how you go about fixing it.
