javascript - 常见的js插件为什么都用连字符命名而不用驼峰？
常见的bootstrap,swiper,slide,fullpage等为什么使用“-”连字符的方式命名而不是使用驼峰？
毕竟驼峰双击一下就能选中，连字符还要选一下。

前端的代码很少见使用驼峰命名法，最常见到的就是连字符，html和css代码皆如此，js使用连字符大概是为了前端代码风格的统一吧
你说的是css的class名称和id名称吧...
这个一般的规则是和原语言保持一致...
css一直就是用-连接的, 比如 border-color, margin-top之类的
html的属性, 也是用-, 因为html属性不区分大小写, 用驼峰会带来很多不便, 比如 <meta http-equiv>, <code><div data-id>
<p>js一直就是用驼峰的, 比如 <code>getAttribute, offsetHeight之类的...
js用下划线的地方也有, 比如自己定义常量的连接 const GLOBAL_LOADDING = ''
不过现在js中变量用下划线的也不少...
语意更清晰，一目了然
用下划线也能双击选中
以清晰,一眼辨别为首要目标
选哪种风格反而不重要.
因为类名的惯例就是使用-连字符，你可以看看sass的语法，默认的就是用-的。
下划线更清晰，我最开始也是驼峰的，后来公司要求下划线，现在再看看驼峰，感觉好XX，特别是不能马上知道标识符的含义
而下划线的，就像是英文单词一样，容易识别理解（把下划线当成空格看，驼峰的是连一起，混）
另外，下划线也可以双击选中啊

How to optimize database performance after mysql installation
Apr 08, 2025 am 11:36 AM
MySQL performance optimization needs to start from three aspects: installation configuration, indexing and query optimization, monitoring and tuning. 1. After installation, you need to adjust the my.cnf file according to the server configuration, such as the innodb_buffer_pool_size parameter, and close query_cache_size; 2. Create a suitable index to avoid excessive indexes, and optimize query statements, such as using the EXPLAIN command to analyze the execution plan; 3.
