Now playing: Ultimate* Generative AI COURSE* for JavaScript Developers | LLMs, LangChain(RAG): Ep.1 | GenAi intro

About this path

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.

What you will learn

  • Explain what Generative AI and large language models are and how they generate responses
  • Set up a JavaScript and TypeScript project for working with LLMs
  • Install Node.js and configure an OpenAI API key
  • Build a first AI-powered app that talks to an LLM
  • Understand what LangChain is and why it is used for AI applications
  • Recognize how RAG, Pinecone and LangSmith fit into AI app development

Who this is for
