計算機科學最難的東西之一

源自一句話

There are two hard things in computer science: cache invalidation, naming things, and off-by-one errors.      

這裡我所說的就是關于命名限制的問題

• 常見命名類型:

• ​​Camel case​​
• ​​Snake case​​
• ​​Kebab case​​
• ​​Pascal case​​
• ​​Upper case (with snake case)​​

• ​​camelCase​​
• ​​snake_case​​
• ​​kebab-case​​
• ​​PascalCase​​
• ​​UPPER_CASE_SNAKE_CASE​​

camelCase

Example ​

​camelCaseVar​

​.

snake_case

Example ​

​snake_case_var​

​.

kebab-case

Example ​

​kebab-case-var​

​.

PascalCase

Example ​

​PascalCaseVar​

​.

UPPER_CASE_SNAKE_CASE

Example ​

​UPPER_CASE_SNAKE_CASE_VAR​

​.

如何選擇?

其實我們所接觸的程式，Java，Python，Go，C系列，Js中都有自己的命名規範，遵守開發規範，能最大程度的提高自己的開發能力

簡單比較下

Case Type	Example
Original Variable as String	​ ​some awesome var​ ​
Camel Case	​ ​someAwesomeVar​ ​
Snake Case	​ ​some_awesome_var​ ​
Kebab Case	​ ​some-awesome-var​ ​
Pascal Case	​ ​SomeAwesomeVar​ ​
