Variables of the Veracious Variety: How to Better Name your Variables
summary
Explains a practical naming method: the three C’s — consistent, concise, correct — and concrete patterns like boolean names that read as questions (isAnyUserActive) and explicit counts (numberOfEligibleDiscountItems). Recommends thesaurus.com to find precise verbs, shows how homonyms and synonyms inflate cognitive load, cites a study where 334 developers had only a 6.9% median agreement on names, and argues for explicit types (e.g., monthAsString, productIdToSuppliersMap) to reduce future refactors.
