• Clean code can be read, and enhanced by a developer other than its original author.
• Code, without tests, is not clean. No matter how elegant it is, no matter how readable and accessible, if it hath not tests, it be unclean.
• Reduced duplication, high expressiveness, and early building of simple abstractions. That’s what makes clean code for me.
• ...You will read it, and it will be pretty much what you expected. It will be obvious, simple, and compelling.
• The designer makes it look ridiculously simple like all exceptional designs.
• It is not the language that makes programs appear simple. It is the programmer that make the language appear simple!
• The next time you write a line of code, remember you are an author, writing for readers who will judge your effort.
• ...the ratio of time spent reading vs. writing is well over 10:1. We are constantly reading old code as part of the effort to write new code.
• Of course there’s no way to write code without reading it, so making it easy to read actually makes it easier to write.
• The cleanup doesn’t have to be something big. Change one variable name for the better, break up one function that’s a little too large, eliminate one small bit of duplication, clean up one composite if statement.

We’re talking about developer experience (DX) here.

I didn’t realize that the ratio of time spent reading vs. writing is well over 10 : 1, and thinking about it, it’s true. I do spend a lot of time reading others’ code (or the code I’ve written sometime before) to figure out what/how to write something.

• “Code, without tests, is not clean” - It mentions how Test Driven Development has made a profound impact upon our industry but I still haven’t really practiced TDD myself. The reason for this wasn’t really elaborated otherwise than that. (”...it has become one of our most fundamental disciplines.”)
