规则
配置规则
ESLint 内置了大量规则，您可以通过插件添加更多规则。您可以使用配置注释或配置文件来修改项目使用的规则。要更改规则设置，您必须将规则 ID 设置为以下值之一：
"off"或0- 关闭规则"warn"或1- 打开规则作为警告（不影响退出代码）"error"或2- 打开规则作为错误（触发时退出代码为 1）
使用配置注释
要使用配置注释在文件内配置规则，请使用以下格式的注释：
/* eslint eqeqeq: "off", curly: "error" */
在此示例中，eqeqeq 被关闭，curly 被打开作为错误。您还可以对规则严重性使用数字等价物：
/* eslint eqeqeq: 0, curly: 2 */
此示例与上一个示例相同，只是它使用数字代码而不是字符串值。eqeqeq 规则关闭，curly 规则设置为错误。
