Jetpack for Android Dev with Kotlin: An Introduction. Covers LocalDB/Network communication.

Introduction to Jetpack (JETPACK) for Android development with Kotlin. You can practice various techniques that can be used while developing Android apps.

This is a fast-paced development course for busy planners. You can learn the entire development process by developing web front-end, back-end, and DB yourself with simple explanations.

This is a basic Kotlin grammar course. Designed for those wanting to develop Android apps in Kotlin, it offers an enjoyable way to build a solid foundation in Kotlin grammar from scratch.

We'll go through a simple tutorial and hands-on practice with Circuit, an Android Jetpack Compose framework.

Let's create a plausible app with Jetpack Compose. Let's advance the example a little and connect the API (Firebase) to do network communication.

Stop telling your designers, “This doesn’t work on mobile.” Jetpack Compose makes it easy to implement UI/animations.

How about moving away from XML-only Android development and introducing Jetpack Compose?

In many programming languages, including Javascript, asynchronous operations are one of the most difficult and complex elements of software. You can discard primitive asynchronous programming such as setTimeout and setInterval and easily handle complex asynchronous operations through RxJS.

Build a solid foundation and confidence by developing a variety of topics from scratch with JavaScript.

You can learn JavaScript from basic to intermediate, which is the foundation of web development.

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.

In this course, you will learn about TypeScript.

This is a lecture on creating a map service from start to finish using the MERN stack (feat. TypeScript). Let's create each part step by step by looking at the official API documentation.

Let's learn from basic syntax to advanced concepts while developing a SPA with vanilla JavaScript🔥

No matter how much you study React, Next.js, or Vue, if the code feels abstract and the structure isn't clearly understood, the root cause might be a lack of understanding of DOM. DOM is the foundation of all frontend frameworks and the entity that connects the structure and behavior of web pages. This lecture goes beyond simple selectors or manipulation methods, teaching step-by-step from the very beginning how HTML transforms into DOM objects and how to select, traverse, and manipulate this structure. It is the Part 1 introductory lecture of 'Complete DOM Mastery'. HTML tags are just structure, and JavaScript is just behavior, but DOM is the core that connects the two. If you clearly understand this connection, you'll be able to precisely grasp the true structure and flow within any framework you use.

Learn core data structures and algorithms such as Stack, Queue, Linked List, Sorting, and DFS/BFS by implementing them directly with JavaScript. Solve frequently appearing problem types together to build problem-solving skills essential for coding tests and interviews.

You will learn the process of developing and launching your own restaurant diary app using React Native. We've prepared the entire process from design to front-end and back-end development, and deployment.

"Becoming a Developer Who Excels at React" has been published. This book provides a solid foundation by systematically guiding you from the basic principles of the web needed before learning React to the latest React hooks. Through over 40 diverse hands-on projects and abundant practical examples, you can apply theory directly to real-world situations and develop problem-solving skills. Additionally, it helps you grow into a developer capable of building high-quality React applications by learning essential modern web development technologies such as Redux Toolkit, Zustand, and Firebase.

New to React? You need to think about how to learn React's fundamental concepts solidly yet quickly. Start with Next.js and JavaScript with minimal knowledge. Let's develop by selecting only the essential examples needed for real-world development. The Todo example is so important that you should develop it twice. Once focusing on components, and then focusing on routing that handles browser paths! Use Zustand for login! You can handle global state with a really small amount of code.

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

You can learn about implementing webcam and peer-to-peer communication using WebRTC.

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.

This is the easiest JavaScript tutorial for those who are starting to code in JavaScript.

Develop your ability to find the core of a problem and solve it with the 'Top 10 JavaScript Algorithms' that cover the most frequently asked types of problems!

Algorithms seem so difficult... Even students who are not good at math can finish the basics of algorithms in one go with this class! We will teach you the basic concepts needed to solve algorithms step by step, and even Codecamp's know-how on applying them to problems :)

The JS Core Theory and Practical Example Textbook and Completed Version for Web Publishers is a lecture textbook produced in PDF format. This textbook helps web publishers to fully acquire the basics of JavaScript and jQuery that they must know. A feature of this textbook is that it allows you to strengthen your theory through small missions connected to the theory. In particular, this textbook is also fully prepared with practical examples that utilize all the theories learned. The entire PDF page contains more than 320 pages of pure JavaScript (Vanilla JavaScript) and jQuery, with sufficient explanations added so that Coding Works can be easily understood. In particular, publishers can learn practical examples of jQuery interactions that are essential for creating websites.

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!
