# no-void

[Added in v0.8.1](https://github.com/web-infra-dev/rslint/releases/tag/v0.8.1)
## Configuration


```ts title=rslint.config.ts
import { defineConfig, js } from '@rslint/core';

export default defineConfig([
  js.configs.recommended,
  {
    rules: {
      'no-void': 'error',
    },
  },
]);
```

## Rule Details

Disallow use of the `void` operator.

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

```javascript
void foo;
void someFunction();

const foo = void bar();
function baz() {
  return void 0;
}
```

## Options

### `allowAsStatement`

When `true`, permits `void` as a standalone statement but still prohibits its
use in expression contexts such as variable assignments or return statements.
Default: `false`.

Examples of **incorrect** code for this rule with `{ "allowAsStatement": true }`:

```json
{ "no-void": ["error", { "allowAsStatement": true }] }
```

```javascript
const foo = void bar();
function baz() {
  return void 0;
}
```

Examples of **correct** code for this rule with `{ "allowAsStatement": true }`:

```json
{ "no-void": ["error", { "allowAsStatement": true }] }
```

```javascript
void foo;
void someFunction();
```
