Research direction
The issue suggests updating DynamoDB examples to use the Document Client. Since the repo is a learning resource for AWS Lambda, the next step is to examine the current examples in the repository (e.g., in the /examples directory) to identify which ones use the old DynamoDB client. Then, refer to the AWS blog post linked in the issue to understand the Document Client API differences. The update involves replacing the old client instantiation (new AWS.DynamoDB()) with docClient = new AWS.DynamoDB.DocumentClient() and using methods like get, put, update, etc. The scope should be limited to a few key examples. No linked PR or assignee, so this is available for a first timer.
