## What it does

Prefer using `Array#toSorted()` over `Array#sort()`.

## Why is this bad?

`Array#sort()` modifies the original array in place, which can lead to unintended side effects—especially
when the original array is used elsewhere in the code.

## Examples

Examples of **incorrect** code for this rule:

```js
const sorted = [...array].sort();
```

Examples of **correct** code for this rule:

```js
const sorted = [...array].toSorted();
```

## Configuration

This rule accepts a configuration object with the following properties:

## allowExpressionStatement

type: `boolean`

default: `true`

When set to `true` (default), allows `array.sort()` as an expression statement.
Set to `false` to forbid `Array#sort()` even if it's an expression statement.

Example of **incorrect** code for this rule with `allowExpressionStatement` set to `false`:

```js
array.sort();
```

## How to use

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

::: code-group

```json [Config (.oxlintrc.json)]
{
  "rules": {
    "unicorn/no-array-sort": "error"
  }
}
```

```bash [CLI]
oxlint --deny unicorn/no-array-sort
```
