no-array-constructor

禁止通用 Array 构造函数.

✅

在 ESLint 配置 中扩展"plugin:@typescript-eslint/recommended" 可启用此规则。

🔧

此规则报告的一些问题可通过 --fix ESLint 命令行选项自动修复。

🧱

This is an "extension" rule that replaces a core ESLint rule to work with TypeScript. See Rules > Extension Rules.

This rule extends the base no-array-constructor rule from ESLint core. 它增加了对泛型 Array 构造函数 (new Array<Foo>()) 的支持。

¥It adds support for the generically typed Array constructor (new Array<Foo>()).

❌ 错误

Array(0, 1, 2);
new Array(0, 1, 2);

✅ 正确

Array<number>(0, 1, 2);
new Array<Foo>(x, y, z);

Array(500);
new Array(someOtherArray.length);

选项

See eslint/no-array-constructor's options.

如何使用

扁平配置

eslint.config.mjs

export default tseslint.config({
  rules: {
    // Note: you must disable the base rule as it can report incorrect errors
    "no-array-constructor": "off",
    "@typescript-eslint/no-array-constructor": "error"
  }
});

旧版配置

.eslintrc.cjs

module.exports = {
  "rules": {
    // Note: you must disable the base rule as it can report incorrect errors
    "no-array-constructor": "off",
    "@typescript-eslint/no-array-constructor": "error"
  }
};
