I couldn't spread undefined

```js
const currentDefinition = {
  inputDescriptors: []
  outputDescriptors: []
}

const inputDescriptors = currentDefinition.inputDescriptors || []
const outputDescriptors = currentDefinition.outputDescriptors || []

const descriptors = [...outputDescriptors, ...inputDescriptors]
```


```js
const currentDefinition = {
  inputDescriptors: []
  outputDescriptors: []
}


const { inputDescriptors = [], outputDescriptors = [] } = currentDefinition

const descriptors = [...outputDescriptors, ...inputDescriptors]
```
