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

不允许重写/重新赋值已有函数。

Javascript 允许对函数定义进行重新赋值。这通常是开发者的错误，或者编码实践不佳，因为代码的可读性和可维护性将受到影响。

无效示例：

function foo() {}
foo = bar;

const a = function baz() {
  baz = "现在我是一串字符串";
};

myFunc = existingFunc;
function myFunc() {}

有效示例：

function foo() {}
const someVar = foo;

const a = function baz() {
  const someStr = "现在我是一串字符串";
};

const anotherFuncRef = existingFunc;

let myFuncVar = function () {};
myFuncVar = bar; // 变量重新赋值，不是函数重新声明
