You've read the blueprint. Now, prove you can build the engine.

This is the official multiple-choice test book and companion guide for AI with JavaScript & TypeScript: Foundations (Volume 1). Reading the theory is the first step; validating your knowledge is what transforms you into a confident AI Engineer.

This test book is designed to bridge the gap between passive learning and active mastery. It's not just a collection of questions; it's a tool to solidify your understanding, identify your weak spots, and prepare you for the technical challenges of building production-ready intelligent applications.

Why This Test Book is Essential for Your Learning Journey:

Solidify Core Concepts: Reinforce your learning and ensure you've truly absorbed the critical patterns and principles from Volume 1.
Prepare for Technical Interviews: Practice with questions that mirror real-world engineering challenges, focusing on architecture, security, and type-safety.
Identify Knowledge Gaps: Discover exactly which topics you need to revisit before moving on to more advanced concepts.

Test Your Mastery Across All Key Areas of Volume 1:

With over 200 carefully crafted questions (10 per chapter), you will be tested on your practical knowledge of:

Secure AI Environments: Can you correctly configure a Node.js environment to handle API keys and secrets?
The OpenAI API in Depth: Do you truly understand the SDK, error handling, and rate-limiting strategies beyond a simple API call?
Type-Safe AI with Zod: Can you write Zod schemas to reliably parse and validate unpredictable LLM outputs into strict, type-safe JSON?
Advanced Prompt Engineering: Can you identify and apply principles like Chain-of-Thought and Few-Shot learning to control model behavior?
LangChain.js Foundations: Can you architect modular AI applications by correctly composing Models, Prompts, and Parsers into executable Chains?

Designed for Effective Learning:

This book is structured to maximize your learning. The first part of the book contains all 200 questions, chapter by chapter, allowing you to test yourself without spoilers. The second part provides a complete answer key with detailed, expert-written explanations that don't just tell you the right answer, but explain the critical \"why\" behind it.

Don't just learn the stack. Master it.

Take the final step in your journey and solidify your skills as a JavaScript AI Engineer today.
