## Rule Details

This rule extends the base [`eslint/no-array-constructor`](https://eslint.org/docs/rules/no-array-constructor) rule.
It adds support for the generically typed `Array` constructor (`new Array<Foo>()`).

<!--tabs-->

### ❌ Incorrect

```ts
/*eslint no-array-constructor: "error"*/

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

### ✅ Correct

```ts
/*eslint no-array-constructor: "error"*/

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

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

## How to Use

```jsonc
{
  // note you must disable the base rule as it can report incorrect errors
  "no-array-constructor": "off",
  "@typescript-eslint/no-array-constructor": ["error"]
}
```

## Options

See [`eslint/no-array-constructor` options](https://eslint.org/docs/rules/no-array-constructor#options).
