在这里插入图片描述

源自一句话

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

这里我所说的就是关于命名约束的问题

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.

如何选择?

其实我们所接触的程序，Java，Python，Go，C系列，Js中都有自己的命名规范，遵守开发规范，能最大程度的提高自己的开发能力

简单比较下

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
Upper Case Snake Case SOME_AWESOME_VAR
