Learning React.js with TypeScript: From Basics to the Latest Technologies Perfectly

Sucoding's 'fifth book',
<AI Self-Study: Creating Your First AI Agent Service> is finally being published.

Are you using ChatGPT only as a tool to ask questions and receive answers? Or are you interested in AI agents but felt overwhelmed about where to start when trying to build one yourself?

This book was written specifically for those people.

It doesn't stop at understanding the core concepts of AI agents; it covers the entire process of building and deploying a functional AI agent service in a single volume.

📖 What you will learn in this book

- LLM calls and prompt design using LangChain
- Chain configuration using LCEL, Runnable, and Output Parser
- Implementation of Tools and AI agents
- ReAct patterns and streaming responses
- Backend API development using FastAPI
- Frontend development using React + TypeScript + Tailwind CSS
- Deploying a service that can be used on the actual internet

As a hands-on project, we will build an AI text analysis service that provides text summarization, sentiment analysis, and style rewriting features.

In particular, this book is structured so that concepts → implementation → service → deployment flow naturally together. Since what you learn in the beginning is applied directly later on, you can build a complete AI agent service just by following along in order.

The explanations are designed to be easy to follow if you know basic Python syntax and the general flow of web development, and I hope it serves as a great starting point for developers and aspiring developers who want to build their own AI services.

If you want to go beyond understanding AI agents and experience building one yourself,
I hope this book helps you.

📢The "Introduction to Python Programming for Beginners" course is now open.

Finally on Inflearn,

👉Python Programming for Beginners has been released.

This course is not just a simple listing of grammar and syntax.

I have carefully designed this course starting from basic concepts so that even those new to programming can understand
“why it works this way.”

In this course,

starting from the development environment setup,
the basic syntax of Python, including

Variables, data types, and operators

Input/Output and String Processing

Conditional statements and loops

Collection data types such as lists, tuples, and dictionaries

Functions and scopes, closures, decorators

Concepts of Classes and Objects

All the way to modules, packages, and exception handling

We have captured the entire core flow of Python from start to finish.

It consists of a total of 13 sections,

From setting up the development environment
to basics → intermediate concepts → structural understanding,
it is designed to progress step-by-step.

Especially the parts that beginners find most difficult

👉 “Combination of conditional statements + loops + collection data types”
👉 “Operating principles of functions and scope”
👉 “Concepts of classes and objects”

I put a lot of thought into organizing this part.

For those who are just starting out with Python,

or for those who have studied it once but
haven't been able to organize the concepts clearly,

Through this lecture,
you will be able to establish a solid foundation.

🔥 Currently offering an early bird discount.

This discount period offers the lowest price,
and it will return to the regular price afterwards.

If you have been wanting to learn Python properly from the very beginning,
this would be a great opportunity to start.

You can check it on Inflearn.
