no-ex-assign

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-ex-assign"],
      "exclude": ["no-ex-assign"]
    }
  }
}

不允许重新赋值异常参数。

一般来说，没有好的理由去重新赋值异常参数。一旦重新赋值，从那时起代码就无法再访问错误。

无效：

try {
  someFunc();
} catch (e) {
  e = true;
  // 无法再访问抛出的错误
}

有效：

try {
  someFunc();
} catch (e) {
  const anotherVar = true;
}
