no-dupe-keys

NOTE: this rule is part of the 推荐 rule set.

Enable full set in deno.json:

{
  "lint": {
    "rules": {
      "tags": ["推荐"]
    }
  }
}

Enable full set using the Deno CLI:

deno lint --rules-tags=推荐

This rule can be explictly included to or excluded from the rules present in the current tag by adding it to the include or exclude array in deno.json:

{
  "lint": {
    "rules": {
      "include": ["no-dupe-keys"],
      "exclude": ["no-dupe-keys"]
    }
  }
}

不允许在对象字面量中使用重复的键。

在对象字面量中多次设置相同的键会覆盖该键的其他赋值，并可能导致意外的行为。

无效：

const foo = {
  bar: "baz",
  bar: "qux",
};

const foo = {
  "bar": "baz",
  bar: "qux",
};

const foo = {
  0x1: "baz",
  1: "qux",
};

有效：

const foo = {
  bar: "baz",
  quxx: "qux",
};
