Becoming a Developer Who's Good at React

Let's conquer React Router, which is essential for everyone who creates SPAs with React 💪

This course is a full-stack level frontend project course that focuses on implementing Notion from start to finish using Vanilla JavaScript, going beyond simple UI cloning to deeply understand the internal operating principles. You'll implement all the core features of a real note-taking app using vanilla JS, including sidebar tree, nested document creation, auto-save, routing, trash, favorites, search modal, settings modal, theme switching, Export/Import, keyboard shortcuts, responsive layout, drag resize, and more. The goal is to solidly learn browser standard behaviors (event bubbling, DOM tree, local storage, Blob, FileReader, hash routing, etc.) that you must know before frameworks like React and Vue, so you can completely understand "why it works this way" and build the skills to debug effectively.

Let's quickly learn React's core design patterns through concepts and examples!

Build and deploy community applications using the MERN Stack (MongoDB, Express, React, Node + Firebase)

A three-in-one class where you can create web games and learn front-end web development skills! This class has been created to teach you how to create games using JavaScript, CSS, and HTML with your own ideas!

Are you a front-end developer and have you ever felt disappointed because you couldn't implement a login function? Have you ever wanted to implement a function that saves and loads data using a DB, but found it burdensome to study queries? With Firebase, it's easy! Let's implement essential functions for web development, such as user authentication, data storage, and hosting, with the power of React and Firebase! (This lecture was recorded in August 22 and reflects the major update of Firebase.)

I will help you learn React Native in the shortest possible time. I will not include any unnecessary parts.

The goal is to acquire basic knowledge of React Native for mobile app front-end development. This course is designed to enable non-experts to easily develop native mobile apps by utilizing languages/APIs with low entry barriers.

This is an intermediate course for developing mobile apps based on React Native. This course is designed to help you develop a complete app that can handle server linkage/login/data transmission/reception/public API utilization, while learning not only the in-depth content of the front-end but also the back-end content based on Firebase.

This is a React-related lecture provided by Life Coding. You will learn how to write components in class and function style in React and examine the differences.

This course is designed to learn the JavaScript programming language along with the latest ES6 grammar.

A portfolio-focused course on directly deploying React frontend and SpringBoot backend to AWS cloud! This course is helpful for those who want to quickly deploy frontend and backend projects to their portfolio! You'll be able to practice step-by-step in a short period the knowledge needed for deployment, from server setup to Docker, Domain connection, Nginx, and HTTPS implementation!

This course goes beyond simply using Express.js. You will rebuild its internal engine from start to finish, gaining hands-on experience with the real principles of how a server works. By directly creating each component of Express—such as routing, middleware, request–response objects, static file handling, and template rendering—you will grow as a server developer and truly understand how a framework operates at its core.

You can learn all about JavaScript, including an overview of the JavaScript language, basic grammar, and provided libraries.

Beyond simply using Express.js, this lecture will have you directly implementing its internal engine from scratch to finish, allowing you to truly internalize the operating principles of a real server. You will directly build all of Express's components, such as routers, middleware, request-response objects, static file handling, and template rendering, from the ground up, providing an experience that fosters growth as a server developer.

jQuery, a JavaScript library used by over 75% of websites worldwide! This course is structured to help you understand the principles and build a strong foundation rather than focusing on flashy effects. Learn jQuery from the basics to advanced applications to complete your own portfolio or use it immediately in the field.

JavaScript, TypeScript Next is backend development! You will be able to develop REST API backends using NestJS, develop and deploy Socket IO.

This is a practical course where you will directly create a timer app using React, Electron, and Zustand, and even deploy it to cross-platforms (Windows, macOS, Linux). Starting with familiar React web development, you can learn the entire flow of desktop app development, including global state management via Zustand and final GUI deployment!

This is a JavaScript-related lecture provided by Life Coding. It is a class on how to handle data immutably in JavaScript.

We will apply it in practice by crawling sites such as Naver, Amazon, Twitter, YouTube, Facebook, Instagram, and unsplash.com.
