unicorn/no-new-array Correctness

This rule is turned on by default.
🚧 An auto-fix is planned for this rule, but not implemented at this time.

作用

禁止使用 new Array()

为什么这不好?

当使用 Array 构造函数并传入一个参数时,不清楚该参数是表示数组的长度,还是表示唯一的元素。

示例

此规则的错误代码示例:

javascript
const array = new Array(1);
const array = new Array(42);
const array = new Array(foo);

此规则的正确代码示例:

javascript
const array = Array.from({ length: 42 });
const array = [42];

如何使用

To enable this rule using the config file or in the CLI, you can use:

json
{
  "rules": {
    "unicorn/no-new-array": "error"
  }
}
ts
import { defineConfig } from "oxlint";

export default defineConfig({
  rules: {
    "unicorn/no-new-array": "error",
  },
});
bash
oxlint --deny unicorn/no-new-array

版本

此规则添加于 v0.0.16。
