The Azure AI Agents JavaScript SDK is a client framework and sample code repository that enables developers to build, customize, and orchestrate AI agents using Azure OpenAI and other cognitive services. It offers support for multi-turn chat, retrieval-augmented generation, function calling, and integration with external tools and APIs. Developers can manage agent workflows, handle memory, and extend capabilities via plugins. Sample patterns include knowledge base Q&A bots, autonomous task executors, and conversational assistants, making it easy to prototype and deploy intelligent solutions.
