# sort-vars

[Added in v0.8.2](https://github.com/web-infra-dev/rslint/releases/tag/v0.8.2)
## Configuration


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

export default defineConfig([
  js.configs.recommended,
  {
    rules: {
      'sort-vars': 'error',
    },
  },
]);
```

## Rule Details

This rule requires identifier variables within the same declaration block to be sorted alphabetically. Destructuring declarations are ignored. By default, ordering is case-sensitive.

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

```javascript
let b, a;
let c, D, e;
```

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

```javascript
let a, b, c;
let G, f, h;
let { b, a } = value;
```

With `{ "ignoreCase": true }`, names are compared without case sensitivity:

```json
{ "sort-vars": ["error", { "ignoreCase": true }] }
```

```javascript
let a, A;
let c, D, e;
```

The rule can automatically reorder declarations when every participating initializer is a literal. It reports without a fix when reordering might change evaluation order.
