## 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>()`).
|
|

|
|
|
### ❌ 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).
