# status becomes the interface Statu

A list of statuses does not become an interface named Status. The converter drops one trailing `s` from the key, then Pascal-cases what is left. `status` becomes `Statu`. `items` becomes `Item`.

This input is `{"status":[{"code":"ok"}]}`.

```ts
export interface Root {
  status: Statu[];
}

export interface Statu {
  code: string;
}
```

And `{"items":[{"id":1}]}` is a different child name:

```ts
export interface Root {
  items: Item[];
}

export interface Item {
  id: number;
}
```

The PHP DTO does not create those interfaces. Both properties are `array`. For the status object the property is `public array $status`, and the constructor line is `$this->status = $data['status'] ?? null`.

## A hyphen survives in the other two drafts

Laravel can quote a hyphen. For `{"first-name":"Ada","role":"engineer"}` the array entry is `'first-name' => 'Ada'`.

TypeScript writes the key as it arrived:

```ts
export interface Root {
  first-name: string;
  role: string;
}
```

The PHP DTO does the same with the property:

```php
public string $first-name;
```

The constructor copies it with `$this->first-name = $data['first-name'] ?? null`. The class around that line is still named `DataTransferObject`. That name does not change. A nested object on the same class is `array`, not a second class, and a missing key is assigned with `?? null` even when the property is `public int $id`.

Rename the class before it ships, and replace a hyphen key with a name the language accepts. The [JSON converter](https://kepttools.com/json-converter) only drafts the text. Conversion runs in the browser.
