🐊[**Putout**](https://github.com/coderaiser/putout) plugin removes useless [Array constructor](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/Array).
It has a different meaning for one, and couple arguments:

```js
const a = new Array(2); // [undefined, undefined]
const b = new Array(2, 3); // [2, 3];
```

## Install

```
npm i @putout/plugin-remove-useless-array-constructor -D
```

## Rule

```json
{
    "rules": {
        "remove-useless-array-constructor": "on"
    }
}
```

## ❌ Example of incorrect code

```js
const a = Array(1, 2, 3);
```

## ✅ Example of correct code

```js
const a = [1, 2, 3];
```
