## 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 ###

*  常见命名类型:
    
     *  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 #

<table> 
 <thead> 
  <tr> 
   <th>Case Type</th> 
   <th>Example</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>Original Variable as String</td> 
   <td><code>some awesome var</code></td> 
  </tr> 
  <tr> 
   <td>Camel Case</td> 
   <td><code>someAwesomeVar</code></td> 
  </tr> 
  <tr> 
   <td>Snake Case</td> 
   <td><code>some_awesome_var</code></td> 
  </tr> 
  <tr> 
   <td>Kebab Case</td> 
   <td><code>some-awesome-var</code></td> 
  </tr> 
  <tr> 
   <td>Pascal Case</td> 
   <td><code>SomeAwesomeVar</code></td> 
  </tr> 
  <tr> 
   <td>Upper Case Snake Case</td> 
   <td><code>SOME_AWESOME_VAR</code></td> 
  </tr> 
 </tbody> 
</table>
