To those who want to learn more, remember that all of this is based on one important principle:

"Programs must be written for people to read, and only incidentally for machines to execute." -Harold Abelson, Structure and Interpretation of Computer Programs

The less reading someone has to do to completely understand how a block of code works, the better your code is. Full stop.

Yes, the code technically has to work. But a large part of the company you work for is already dedicated to that. QA, product owners, bug tracking systems, junior devs--there are plenty of people thinking about whether your code works. That will take care of itself. But probably the only person thinking about the readability of your code is yourself.

All eight of the rules I've described are aimed at making your code blocks short, expressive, and easy to understand ("easy to delete" is a variant of this). But you'd get by just fine if you approached each block of code (and the program itself) in terms of its grokability. Remember that your audience is not the compiler/interpreter/browser--your audience is a junior dev with a short attention span. Keep things short, explicit and to the point.
