“Programs are meant to be read by humans and only incidentally for computers to execute”
— Donald Knuth
- Write intent revealing names. If the variable stores the last updated record, name it ‘lastUpdatedRecord’, not just ‘record’, or even ‘lastRecord’
- Make clear distinctions. What kind of info will ‘ProductInfo’ has that the ‘ProductData’ won’t?
- Add context to names. Put variable state in well-named classes.
- Don’t abbreviate. Say ‘getWindow’ not ‘getWin’
- Pick one word per abstract concept & stick with it. What’s the difference between fetch and retrieve? pick and use only one
- Don’t pun, don’t make your readers mentally map names to something else.
- Use conventions for common operations.
- Avoid similar sounding & easily misspelled names
- Favor readability over brevity
