It then runs that promise, and in the `then()` block (successful case) calls the handler callback inputting data and in the `catch()` block (unsuccessful case) calls the handler callback inputting the error. At MK Decision we use promisified AWS SDK functions as much as possible, but a different way (the way the [AWS SDK documentation](https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/DynamoDB.html#putItem-property) uses) would be something like this:
