The code examples in this directory demonstrate how to work with Amazon DynamoDB using the AWS SDK for JavaScript version 3 (v3).
Amazon DynamoDB is a key-value and document database that delivers single-digit millisecond performance at any scale. It's a fully managed, multiregion, multimaster, durable database with built-in security, backup and restore, and in-memory caching for internet-scale applications.
