@babel/plugin-transform-dotall-regex

信息

此插件包含在 @babel/preset-env 中，在 ES2018 中

¥This plugin is included in @babel/preset-env, in ES2018

此插件转换正则表达式字面量以支持 /s 标志。它不会修补 new RegExp 构造函数，因为它的参数不能静态地预先转换：要处理函数/类的运行时行为，你需要改用 polyfill。

¥This plugin transforms regular expression literals to support the /s flag. It does not patch the new RegExp constructor, since its arguments cannot be pre-transformed statically: to handle runtime behavior of functions/classes, you will need to use a polyfill instead.
