It was a great lecture that was too good to be considered a free lecture. In particular, I learned a lot from the systematic step-by-step explanation of why it is necessary to handle asynchronous functions, how it has been used, and why it was made that way. This time, too, it was a lecture that I trusted and listened to by Pangyo.~~

Thank you for your valuable lecture. Stay healthy always.
JavaScript development
JavaScript Basic Syntax
ES6+
This is a course where you can learn JavaScript fundamentals and modern syntax in a compressed format within a short time, which you must know before learning frameworks like React and Vue. The course is structured so you can learn just what you need when developing web applications with modern frontend frameworks :)
Beginners
starting frontend development
I don't know what to learn first when starting FE development. How much JavaScript do I need to know?
JavaScript syntax
People who sort of understand but find it confusing
I learned React and Vue, but I don't know JavaScript syntax precisely. export default, async await, ..., then & catch, () => {} 😵💫
For those whose heads hurt
from lexical scope and prototypes
In practice, you can develop sufficiently without knowing these concepts. Learn only the necessary concepts in a practical way :)
You'll master the JavaScript basics and modern syntax needed to use frameworks.
You can build a strong foundation in the most important aspects of practical development: working with arrays, asynchronous processing, and modularization syntax.
JavaScript won't seem that difficult. We'll teach you only the essential syntax in an easy way :)
Learn and review with comprehensive web materials that go beyond the class content
We provide website course materials so you can easily review what you learned in class. You can study additional topics you're interested in for free ❤
Short explanations, easy and ample practice
No matter how simply I explain it, difficult things are still difficult. I keep explanations as short as possible, covering only what's necessary, and explain things easily through code 😄
You'll learn the fundamentals of JavaScript including variables, functions, loops, conditionals, objects, arrays, and more. You can also easily learn about first-class functions, one of JavaScript's most important features :)
The latest syntax was designed to write existing JavaScript syntax more concisely and quickly.
Rather than simply memorizing the syntax, we'll also explain the background of why it's written this way.
You can also take a complete journey through asynchronous processing, an important concept in JavaScript, from callbacks to async, await :)

"People Inflearn Met" Interview
Q1. It seems like this is the first free course you've uploaded on Inflearn in 8 years. What prompted you to do this?
The reason I hadn't created a separate JavaScript course before was because I explained all the necessary JavaScript syntax throughout the Vue.js course roadmap. This time, while creating the React learning roadmap, I thought it would be necessary to have a video explaining the basic and essential JavaScript syntax.
Just as I received help from free videos like CodeSchool and Opentutorials when I first learned JavaScript, I decided to open this for free for the developer ecosystem :)
I hope you can also experience the enlightenment and joy I felt from good lectures ❤
Q2. Do I need to know HTML and CSS to take this course?
No. Since this is a class for understanding the basic concepts and syntax of JavaScript, you don't need to know HTML or CSS. While JavaScript has the ability to manipulate HTML and CSS, this aspect is not covered in the course. Still, since it's a free course, feel free to sign up and give it a try without any pressure :)
Q3. I already know some JavaScript (junior developer, professional) - should I still take this course?
Yes. Since it's a free course, you can check the curriculum and just learn the parts you need. If you already know basic syntax like variables, functions, conditionals, and arrays, you'll gain something by looking at ES6+ modern syntax and asynchronous processing :)
Q4. What course should I take next after completing this course?
I recommend following the learning roadmap provided on the course introduction page, either the React Learning Roadmap or the Vue Learning Roadmap. Depending on your learning goals, if you're aiming for employment, I'd recommend following the learning roadmap, and if your goal is personal business or product development, it would be good to pick what you need from the full course list :)
Q5. I want to learn more advanced content.
Amazing JavaScript was named after the Amazing Spiderman series. Just as there are multiple Spiderman movies, we plan to film follow-up courses for JavaScript at beginner, practical, and advanced levels. Please take the course and leave reviews so that your energy and support can help us bring you content more quickly :)
Operating System and Version (OS): The course uses Mac, but all Windows-related shortcuts are also explained.
Tools used: The course uses only the Chrome browser without installing any separate development tools.
A web textbook and blog are provided where you can learn more extensive content in an engaging way beyond what's covered in class.
We also provide many free educational videos throughout the course where you can easily learn the topics mentioned 🎁
This class is best suited for those who have programmed at least once in other languages such as C, Java, or Python.
