AWS SDK for JavaScript v3 is a modular AWS SDK for building JavaScript and TypeScript apps that call Amazon Web Services. It provides separate packages for each service, first-class TypeScript support, and a middleware stack, making it useful for projects targeting services like DynamoDB, Lambda, and S3.
