DynamoDB - with Serverless
What will the following Lambda function return if the DynamoDB table 'Orders' is empty?
```javascript
const AWS = require('aws-sdk');
const docClient = new AWS.DynamoDB.DocumentClient();
exports.handler = async () => {
const params = { TableName: 'Orders' };
const data = await docClient.scan(params).promise();
return data.Items.length;
};
```
