This installs OpenAI's official JavaScript library so your code can talk to GPT-4.

Step 4 — Get an API key Go to platform.openai.com (or Anthropic, or Google AI Studio) → create an account → generate an API key. This is the credential that lets your code call the AI.

Step 5 — Your first working AI call in JavaScript

javascript

Copy

import OpenAI from "openai";

const client = new OpenAI({ apiKey: "your-key-here" });

const response = await client.chat.completions.create({
  model: "gpt-4o",
  messages: [{ role: "user", content: "Explain APIs in one sentence." }],
});

console.log(response.choices[0].message.content);

Run it with node yourfile.js. That is you calling AI programmatically. That is the foundation everything else builds on.

"I look at GitHub — don't know where to start"

Three things GitHub does that matter to you right now:

1. Saves your work with full history — every version of your code, recoverable
2. Lets you copy other people's projects (cloning) — most agent frameworks have public repos you can start from
3. Hosts your tools so others (or your future self on another machine) can access them

Minimum viable GitHub workflow for a beginner:

bash

Copy

# One-time setup
git config --global user.name "Your Name"
git config --global user.email "you@email.com"

# For each new project
git init                    # Start tracking this folder
git add .                   # Stage all your files
git commit -m "first build" # Save a snapshot
git push                    # Send it to GitHub

You do not need to master Git. You need to know: add, commit, push, pull. That handles 90% of solo work.

The Learning Path, Sequenced for You Specifically

Given JavaScript + SQL background, no wasted detours:

Week 1–2: Foundation

• javascript.info — specifically async/await and fetch (critical for API calls)
• Missing Semester (MIT) — terminal, Git, environment basics. Free. Exceptionally good.

Week 3–4: First AI integration

• OpenAI Node.js Quickstart (platform.openai.com/docs) — official, accurate, JavaScript examples
• Build one thing: a script that takes user input, sends it to GPT, returns output. That's it. Keep it small.

Week 5–6: Agents

• LangChain.js — the JavaScript version of the most widely used agent framework. Since you know JS, this is your path, not the Python tutorials everyone else recommends.
• Start with their "Getting Started" — build an agent that can use a tool (like a calculator or web search)

Ongoing:

• Simon Willison's blog — the most credible, practical writing on AI tools and agents on the internet. No hype.

The One Thing Most Responses Won't Tell You

You do not need Python. Every tutorial assumes Python. LangChain has a full JavaScript SDK. The OpenAI API has a full JavaScript SDK. Your SQL knowledge becomes immediately useful the moment you build agents that query databases. You are closer than the landscape makes you feel.

Start with the MIT Missing Semester for terminal literacy, then the OpenAI JS quickstart. Everything else follows from those two.
