    { id: '1', sentence: "She goed to the store.", correction: "She went to the store." },
    { id: '2', sentence: "They plays video games all day.", correction: "They play video games all day." }

})

// Access a specific example
const exampleLabel = dataset.getRow(2).sentence;

// Save the dataset
const ref = await dataset.save()
```
