Learning Concurrency and Functional Programming with TypeScript (Wednesday Coding Session ep.1)

This is a course where you can learn ES6+ and functional programming. This course covers and applies the iterable/iterator/generator protocols of ES6+ in detail. You can learn functional programming based on iterables, map/filter/reduce, pipelines, lazy evaluation through generators, promise composition, concurrency/parallelism, async/await and asynchronous error handling, etc. Master this course and practice to become an intermediate JavaScript developer!

Cultivate advanced programming language utilization skills and software design and implementation skills combining functional, object-oriented, and LISP paradigms, necessary for growing into a mid-to-senior level developer.

This course is a series of courses on functional programming and JavaScript ES6+, covering a variety of application cases.

This is a lecture on functional programming by CTO In-dong Yoo of Marpple (http://www.marpple.com). You can create your own library with functional programming and experience the paradigm of functional programming and the joy of coding.

Regardless of the field! This is a lecture that covers the core fundamentals that developers must know in practice in an easy + code-oriented way. I highly recommend this lecture to all junior developers and job seekers who want to grow.

This is the practical application part of "TypeScript Introduction - From Basics to Practical Use." If you haven't taken the introductory course, please take the introductory course first 😄

This is a lecture for those who are starting out with TypeScript. The curriculum is designed to make it easy for even those who don't know the latest JavaScript grammar to learn. Let's learn TypeScript, which can seem difficult, in an easy and fun way from the perspective of a beginner 😄

How to Use Storybooks A to Z. We show you everything about storybooks.

Quickly learn TypeScript's syntax and usage with the easiest explanation.

We will develop a web app that collects data using concurrent/parallel programming in Python, loads it into MongoDB, analyzes it, and visualizes the collected data using FastAPI, a modern web framework. In the process, you will learn and understand Python concurrent/parallel programming using coroutines, multi-threading, and multi-processing, and understand how to use them to improve Python's performance. We will help you apply Python concurrent/parallel codes directly to your work. We will not only teach you how to develop and end, but also how to deploy and operate an actual app on the AWS cloud.

Scala allows you to write much more concise and robust code quickly, while still leveraging the experience you have gained as a Java developer. This course is designed for Java developers to quickly understand the overall look of Scala based on their existing Java knowledge. If you are an existing Java developer, you can learn Scala very easily.

This course is for developers who have already used programming languages (Java/Python/Swift/Kotlin, etc.). It is a lecture designed to quickly learn JavaScript in one hour. Although we are in an era of coding with AI, human developers must supervise AI code. Therefore, this lecture aims to quickly build the minimum knowledge needed for supervision.

Covers Swift Concurrency from A to Z. (Part 1)

We develop an avatar-based community app with React Native. You'll learn to build a comprehensive community app, covering post creation, comments/replies, likes, voting, avatar generation, etc.

An in-depth TypeScript course for top web developers. You'll grasp TypeScript's essence upon completion, mastering React, Next, Nest, and more.

You will learn about what a node is, the latest JavaScript grammar, the node API, npm, the module system, databases, testing, and more. You will create a project using five practical examples. You will also deploy a service to the cloud and convert a node project to TypeScript.

This is a lecture on functional programming by CTO In-dong Yoo of Marpple (http://www.marpple.com). You can create your own library with functional programming and experience the paradigm of functional programming and the joy of coding.

I recommend this to those who want to learn how to easily create and distribute Android apps, Windows apps, and iOS apps. We will teach you the basics of TypeScript rather than JavaScript and Angular!

In this course, you will be able to create a Reddit website from scratch, step by step.

Building React User Registration, Login + Board with Vibe Coding (React + FastAPI) is a hands-on course where you directly complete a full-stack web application using AI prompts. OpenAI Codex and Claude Code In this course, you'll connect a React (TypeScript) frontend with a FastAPI backend to implement: User registration & login functionality Board CRUD (create, read, update, delete) JWT authentication and authorization handling all within a single project. Particularly, rather than just stopping at writing code, 👉 AI prompt code generation → execution and modification → testing → expansion Through this "Vibe Coding" learning approach, you can experience a new development flow of working together with AI. After completing the course, you'll be able to directly finish your own "member-only board service," and additionally challenge yourself with extended features like comments, likes, and image uploads.

Learn Springboot + NextJS RestAPI Board Creation Faster Than Anyone Develop a CRUD server with Springboot and create your own board with NextJS!

API server built with Spring Boot (Spring Boot ver3.4.x) and React 19 (with TypeScript) Completing the integration project! Producing the entire portfolio writing bootcamp as lectures.
