抛出错误时需要 new。
¥Require new when throwing an error.
虽然可以在不使用 new 关键字的情况下实例化 Error,但最好保持一致:现代内置函数需要实例化 new。
¥While it’s possible to instantiate Error without using the new keyword, it’s better to be consistent: modern builtins require new to be instantiated.
当规则名称以单词 “错误” 结尾且第一个字符为大写时,规则会匹配错误。
¥Rule matches errors when their name ends with the word “Error” and the first character is uppercase.
