Now playing: Ultimate* Generative AI COURSE* for JavaScript Developers | LLMs, LangChain(RAG): Ep.1 | GenAi intro
This learning path follows a YouTube playlist by coding with LuLu. It starts with what Generative AI and large language models are, then moves into setup with Node.js, TypeScript and an OpenAI API key. From there you build your first AI app, learn LangChain, and continue toward RAG, Pinecone and LangSmith. The playlist is ongoing, so later episodes may be added over time. Lessons are short and hands-on, with coding in JavaScript and TypeScript.
