强制一致地使用反引号、双引号或单引号

一些该规则报告的问题可以通过 --fix 命令行选项 自动修复

JavaScript 允许您以以下三种方式之一定义字符串：双引号、单引号和反引号（从 ECMAScript 6 开始）。例如：

/*eslint-env es6*/

var double = "double";
var single = 'single';
var backtick = `backtick`;    // ES6 only

这些行中的每一行都创建一个字符串，在某些情况下，可以互换使用。选择如何在代码库中定义字符串是模板字面（允许解释嵌入的表达式）之外的一种风格。

许多代码库要求以一致的方式定义字符串。
