## One Responsibility per Module

```js

export function createUser() {}
export function connectToDb() {}
```

```js
// ✅ Good
// user.service.js
export function createUser() {}
```

## Export Patterns

```js
// ✅ Prefer named exports
export function parseDate() {}
export function formatDate() {}
```

/users
  user.service.js
  user.repository.js
  user.controller.js
```
