For example, use `unorderedNumbers` and `orderedNumbers` instead of a generic `numbers`. 4 -* **Avoid Misinformation** 5 - * Steer clear of ambiguous, easily confused names or characters (e.g., l vs. 1, O vs. 0). 6 -* **Clarity in Differences** 7 - * Distinguish names distinctly, avoiding similar expressions and redundant words (e.g., a, an, the, info, data). 8 -* **Pronounceable and Searchable Names** 9 - * Use names that are easy to pronounce and discuss. 10 - * Name length should match its scope: short for local loops, longer for broader usage. 11 -* **No Encodings or Mental Mappings** 12 - * Avoid including type or scope information in names. 13 - * Names should be clear without requiring mental translation, meaning any effort of the programmer to get the actual purpose 14 -* **Naming Conventions for Classes and Methods** 15 - * Class names: Use nouns or noun phrases. 16 - * Method names: Use verbs or verb phrases, adhering to standards like JavaBean (get, set, is, has). Utilize descriptive function names instead of overloaded constructors. 17 -* **Avoid Inappropriate Humor and Ambiguities** 18 - * Refrain from humorous names. 19 - * Choose one word per concept to maintain consistency (e.g., always use "get" instead of alternating with "fetch" or "retrieve"). 20 - * Avoid puns and ambiguous terms (like "add" for addition or appending). 21 -* **Domain-Specific Naming** 22 - * Use technical terms (solution domain) for clarity among programmers. 23 - * Use terms from the problem domain when no technical equivalents exist, aiding domain experts. 24 -* **Context and Simplicity in Naming** 25 - * Provide meaningful context through combined variable and method names. 26 - * Avoid unnecessary context; opt for shorter, meaningful names. 27 - * Be open to renaming for clarity and improvement. 1 +Names should be chosen as carefully as the name of your first-born child. It should be obvious from reading the code how it works. 2 + 3 +* **Names describe purpose.** For example, it's better to have a variable `unorderedNumbers` which is sorted and stored in `orderedNumbers` than to store both lists in the same variable `numbers`. 4 +* Avoid misinformation.** For example, ambiguities, confusion with similar names, or easily confused characters (l and 1, O and 0). 5 +* Avoid very similar expressions and empty words that are redundant (a, an, the, info, data). 6 +* Use pronounceable names.** Programming is a social activity that people talk about with others. 7 +* Searchable means avoiding search conflicts with other independent things with the same name. The length of a name should match the size of its scope. For local counting loops, one letter is sufficient; if the variable is used in multiple places in the code, it needs a longer name. 8 +* There should be no references to the scope or type of the variable in the name. 9 +* Avoid mental mappings.** The name of a variable should not require mental effort to understand. For example, unusual abbreviations should be avoided. 10 +* Class names consist of nouns or substantivistic expressions. 11 +* Method names consist of a verb or an expression with a verb. Accessors, mutators, and predicates should be named after their value and follow the JavaBean standard (prefixes: get, set, is, has). For example, getAge(), setAge(...), isFeatureXEnabled() -> boolean, hasPermission() -> boolean, etc. 12 +* Use object creation functions rather than overloaded constructors, as the latter can cause confusion. Overloaded constructors should be declared private, and functions should be used to create instances whose names make the difference clear. 13 +* No puns or humorous names. 14 +* For example, if you use the word "fetch" once for a particular concept, you should consistently use "fetch" instead of synonyms such as "retrieve. 15 +* Avoid ambiguity, as in the word "add" (addition or adding). 16 +* Domain-specific terms 17 + * Use terms from the solution domain. Programmers will be reading your code, so use technical language. 18 + * Use terms from the problem domain. If there are no computer science terms, at least domain experts can refer to them. 19 +* Add meaningful context.** Along with other variables' and methods' names, context can be created. 20 +* Shorter names are better than longer ones, as long as they are clear. 21 +* Don't be afraid to rename things. Your colleagues should be grateful for improvements.
