# no-empty

[Added in v0.2.2](https://github.com/web-infra-dev/rslint/releases/tag/v0.2.2)
## Configuration

| Preset                   | Configured Value |
| ------------------------ | ---------------- |
| ✅ js.configs.recommended | `"error"`        |


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

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

## Rule Details

Disallow empty block statements. Empty block statements, while not technically errors, usually occur due to refactoring that wasn't completed. They can cause confusion when reading code.

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

```javascript
if (foo) {
}

while (foo) {}

switch (foo) {
}

try {
  doSomething();
} catch (e) {}
```

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

```javascript
if (foo) {
  // empty
}

while (foo) {
  /* todo */
}

try {
  doSomething();
} catch (e) {
  // expected
}

function foo() {}
```

## Options

- `allowEmptyCatch`: If `true`, allows empty `catch` clauses (i.e., which do not contain a comment). Default: `false`.
