newline-after-var

此规则在 ESLint v4.0.0 中已弃用，并被 padding-line-between-statements 规则取代。

到今天为止，将变量声明与其余代码分开还没有一致性。一些开发人员在 var 语句和其余代码之间留了一个空行，例如：

var foo;

// do something with foo

而其他人根本不会留下任何空的换行符。

var foo;
// do something with foo

问题是当这些开发人员在一个项目中一起工作时。此规则强制执行编码样式，在 var、let 或 const 语句之后允许或禁止空换行符。它有助于代码在整个项目中看起来一致。
