2024 Renewal Version
React cut into bite-sized pieces
Towards the world's friendliest and easiest React course

From JavaScript basics,
React.js real-world project

React.js is a JavaScript library that runs on Node.js.
So, in the end, React.js is just a tool to help you get better use out of JavaScript.
Therefore, if you do not have a good understanding of JavaScript and Node.js, you cannot utilize React.js properly.

This course will teach you JavaScript basics, Node.js, and React.js.
But it’s not fun if you just learn it! You will learn React.js through a total of 3 projects .
Through this process, you will develop into a front-end developer with solid fundamentals.

18 hours worth
A total of 3 React.js projects

This course is not just about teaching you how to use React.js.
We also cover various CS knowledge surrounding React.js, and a total of 3 projects.
You can develop your programming thinking skills while creating a counter app, to-do list, and emotion diary.


Lecture Structure

📌 Section 1~2. JavaScript Basics and Advanced

Before learning React.js, let's look at the basic and advanced concepts of JavaScript.
From basic concepts such as data types and operators,
We will also look at more advanced topics such as array methods and asynchronous tasks.

Even if you already know JavaScript, it's a good idea to look through it again for a refresher.

📌 Section 3. Node.js

React.js is a technology that operates on top of Node.js. Therefore, you cannot know React.js without knowing Node.js.
In Section 3, we will look at what Node.js is, why it was created, and what features it has, with hands-on experience.

📌 Section 4. Introduction to React.js

Let's find out what React.js is, how it differs from other technologies, and take a closer look at how it solved the limitations of existing technologies. In the process, we will gain a deeper understanding of React.js.

📌 Section 5. Introduction to React.js

Create a new React App and explore the basic features of React, such as Components, State, and Props.
You will learn all the basic functions with hands-on exercises and fully understand them visually with illustrated materials.

⛳️ Section 6. React.js Project 1. Counter App

Let's create our first React project, "Counter App".
It's a simple project, but it's a good way to get a glimpse into how React.js works and its design philosophy.

📌 Section 7. Life Cycle

Just as all humans are born and go through infancy, adolescence, youth, old age, and reach twilight, all React components are born, change, and disappear. This life cycle of a component is called a life cycle.

Understanding and controlling the lifecycle of a component will allow you to perform the actions you want at the time you want. So in Section 7, we will look at the lifecycle and how to control it with practice.

⛳️ Section 8. React.js Project 2. To-do List

Let's create our second React project, "Todo List App".
While implementing this project, we implemented data CRUD (add, lookup, modify, delete) and search functions.
We'll look at several ways to handle array-like data in React.

📌 Section 9. useReducer - Separating state management logic

Separation of code by role is always a virtue in software development.
Let's take a look at useReducer, which helps separate complex state management code.
Practice by applying it directly to a to-do list project.

📌 Section 10. Optimization

If there are any unnecessary operations in our project, we should remove them boldly!
Let's take a look at several optimization techniques for React Apps that eliminate wasteful computation.
Practice by applying it directly to a to-do list project.

📌 Section 11. Context

Let's take a look at Context, which provides data to various components in a more concise and clean way.
Practice by applying it directly to a to-do list project.

⛳️ Section 12. React.js Project 3. Emotion Diary

Let's create our own final project emotional diary using all the concepts we've learned so far.
Additionally, we use the browser's database and deploy the project to make it accessible to users.
Demo link: https://emotion-diary.winterlood.com/

📌 Section 13. In conclusion

The lecture ends, but our learning does not.
Let's talk about what direction we should take going forward.


The Kindest in the World
4 Principles for React Teaching

📣 Rule 1. Always explain in a simple, friendly, and visual way.

No matter how complex and difficult the content is!
We have worked hard to make it easy to understand and friendly with visual aids.
These are all images I created myself, so you can capture them and use them in your learning blog posts. 😃

📣 Rule 2. Pronounce it so that it can be heard even when played at high speed.

If you're listening again to review, or if you're in a hurry, listen at high speed!
We took special care to ensure that your pronunciation is audible up to 2x speed 😎
(Take a listen to the video below, played at 1.5x speed!)

📣 Rule 3. Save your code so it’s easy to find

Wouldn't it be a shame to just keep the practice codes you worked so hard to write?
I took care to organize the code into sections so that I could always go back and look at it again.
Code repository link: https://github.com/winterlood/onebite-react-v2

📣 Rule 4. Communicate constantly

Gather in a student-only community to share knowledge and news with one another and grow.

    I actually bought the lecture for a thousand won on April Fool's Day... just in case, like the lottery... But it really feels like I won the lottery. I feel bad that I'm able to listen to and study such a good lecture at almost no cost... The lecture is so kind, and the examples are explained so clearly that I really love it. Thank you so much, and I love you... 😭😭

        I haven't watched them all yet, but from my perspective of having purchased several React lectures, this lecture is the best. Other lectures must have been created by experienced JavaScript developers. However, there is a problem. Experienced people give lectures while already having an image of how the code works in their heads. So, they give lectures while writing code like Uncle Bob. However, for beginners, it is frustrating to just follow the code without being able to visualize what is happening at all, and it is difficult to even grasp the concepts. In this lecture, before the code, the concept is explained by first visualizing what happens when a certain function is used, and then the code is shown, so I also get an image of the code working in my head while looking at the code. Most instructors are developers, not educators/education majors, so I feel that there are too many lectures being mass-produced without a standard for this effective teaching method, but this lecture is really the best. I have already purchased TypeScript before I have even watched the entire lecture. The quality is good, but the lecture fee is too much. I even bought the book so that I could have another cup of coffee. I don't often use the expression 'thank you' for lectures that I pay for with my own money, because it feels strange. Nevertheless, this lecture is 'very grateful'. If possible, I think it would be good if you also give lectures on Express.js, Next.js, and TDD!

          I took React in English on a third-party site first. Since I was taking the course without a 100% understanding of English, I misunderstood the concepts or had problems with the explanations. So I looked for a React course on Inflearn and it looked good, so I took it. The course started from JavaScript again, so I was able to study JavaScript as well, which was great. I also learned a lot about React because it explained the concepts well. One thing that was disappointing was that when explaining A->C, there were a few parts where it would have been much easier to understand if the course had explained B in the middle, like A->B->C. Many other people also left questions about these in the Q&A section of the lecture. If only these parts could be improved, I think this would have been a perfect course.

            This price is ridiculous for such an explanatory power and content. I think I could have paid double, but it's really a lecture like "The boss is crazy".. It's hard to say that I've digested it all yet, but I'll try to master it through repeated study. Thank you for making such a great lecture :) !!
