But documentation isn’t the only way to show intent, while I believe code does require documentation much of documentation can be replaced with well written code.

Lets get straight into some examples:

1. Language

The great thing about clean code is the reader doesn’t have to be an expert on the domain to appreciate its beauty. The same concept applies to intent, by taking a little thought
