## 📚 Usage Examples


### Python Example


```python
from kore import KoreWriter, KoreReader

# Write data

writer = KoreWriter("data.kore")
writer.write({
    "id": [1, 2, 3],
    "name": ["Alice", "Bob", "Charlie"],
    "age": [25, 30, 35]
})
writer.close()

# Read data

reader = KoreReader("data.kore")
data = reader.read()
print(data)  # Fast and memory-efficient
```

### Rust Example


```rust
use kore::KoreWriter;

fn main() {
    let mut writer = KoreWriter::new("data.kore").unwrap();
    // Write your data
    writer.flush().unwrap();
}
```

### Java Example


```java
import com.kore.KoreWriter;

public class Main {
    public static void main(String[] args) {
        KoreWriter writer = new KoreWriter("data.kore");
        // Write your data
        writer.close();
    }
}
```

### JavaScript Example


```javascript
const { Kore } = require('kore-fileformat');

async function main() {
    const schema = {
        fields: [
            { name: 'id', type: 'int64' },
            { name: 'value', type: 'float64' }
        ]
    };
    
    const data = [
        { id: 1, value: 10.5 },
        { id: 2, value: 20.3 }
    ];
    
    // Write your data
    await Kore.write('data.kore', schema, data);
}

main();
