```

Example for boolean:
```json
{
  "answer": "true",
  "bool": true
}
```

### Text Format

The text format returns the raw input as a string.

Example:
```
your_input_here
```

```typescript
const input = new Input();

(async () => {
  const response = await input.prompt({

  console.log(`Your favorite color is ${response}`);
})();
```
