brace-style

对块执行一致的大括号样式

一些该规则报告的问题可以通过 --fix 命令行选项 自动修复

大括号样式与编程中的 缩进风格 密切相关，描述了大括号相对于其控制语句和主体的位置。世界上可能有十几种（如果不是更多的话）牙套样式。

一种真正的大括号样式是 JavaScript 中最常见的大括号样式之一，其中块的左大括号与其对应的语句或声明位于同一行。例如：

if (foo) {
  bar();
} else {
  baz();
}

一种真正的大括号样式的一种常见变体称为 Stroustrup，其中 if-else 构造中的 else 语句，以及 catch 和 finally，必须在前一个右大括号之后单独一行。例如：

if (foo) {
  bar();
}
else {
  baz();
}
