object-shorthand

要求或禁止对象字面量的方法和属性简写语法

一些该规则报告的问题可以通过 --fix 命令行选项 自动修复

ECMAScript 6 为定义对象字面量方法和属性提供了一种简洁的形式。这种语法可以使定义复杂的对象字面量更加清晰。

以下是一些使用 ES5 语法的常见示例：

// properties
var foo = {
    x: x,
    y: y,
    z: z,
};

// methods
var foo = {
    a: function() {},
    b: function() {}
};

现在这里是 ES6 等价物：

/*eslint-env es6*/

// properties
var foo = {x, y, z};

// methods
var foo = {
    a() {},
    b() {}
};
