Why you should learn asynchronous programming!
JavaScript, an event-driven language
JavaScript is an event-based programming language designed to provide dynamic functionality to browsers. JavaScript programs handle events using callback functions, using APIs provided by the browser or Node.js system. Therefore, developing applications in JavaScript requires a thorough understanding of asynchronous programming.
The Promise object, included in ES6 in 2015, and the await and async keywords included in ES2017 provide a way to easily program asynchronously executed functions to be executed synchronously as desired .
Have you ever used the Promise object, or the await or async keywords in your JavaScript code? If you're just starting out with JavaScript development, they might feel unfamiliar or unfamiliar. Of course, many modules already provide these keywords, so you've probably already used them.
How does asynchronous programming work? 🤔
If you're curious about how the two programs below work and what output they produce, this lecture is for you!
In this lecture, we will start with the Callback function and then explain the meaning and usage of the Promise object and the await and async keywords one by one.

Asynchronous programming in JavaScript
Complete explanation from start to finish
💡 This course is intended for those who have learned the basics of JavaScript . Basic knowledge (variables, functions, if statements, loops, etc.) will not be explained separately.
Section 1-1
This course covers the history of JavaScript, its origins, and the meaning of asynchronous programming. Learn how to register callback functions and handle user events in the browser.
Section 1-2
This article explains how a Node.js-based web server works. We'll also explore the case of callback hell.
Sections 1-3
Explains asynchronous programming using callbacks.
Sections 1-4
Learn about asynchronous programming using the Promise object.
Sections 1-5
Learn about asynchronous programming using the await-async keyword.
Sections 1-6
You will learn about concurrent programming using asynchronous functions.

4 Study Tips for Students
- ✅ If you try to understand something by running it first and then looking at the results, your skills will not improve.
- ✅ Read the program, imagine how it will work, and predict the results.
- ✅ You can't learn just by seeing and hearing.
- ✅ Write the code you want.
💾 Training Environment Guide
- This tutorial will be conducted in a Node.js environment. We recommend installing the latest version.
- I use Visual Studio Code as my IDE, but you can use any other IDE.

100% enrolledThis was exactly the lecture I wanted. I like it because I can learn the browser operation process in detail. The flow of understanding is still slow, but if I watch it repeatedly and get used to it, I think I will be able to quickly understand the flow even when looking at long codes. Thank you.

67% enrolledBecause the runtime is short, I listened to it all at once as if I was listening to a liberal arts lecture :) I knew about asynchrony and used it when working on projects, but I thought I didn't understand it properly, and I think this lecture explained those parts well from the basics. If there is anyone who is studying the basics of JavaScript and wants to learn about asynchrony properly, I think it would be good to take this lecture. Additionally, it would be good if there was a follow-up lecture that gave a simple example of how to use asynchronous programs in practice. The instructor's voice was also very good, and I listened with satisfaction. Thank you.

I'm so touched because this is my first class review^^ Many Node.js modules already support promises, so I think it wouldn't be difficult to develop without them. Especially if you're doing backend development related to DB. I think it would be good to look at Prisma (prisma.io). You can also test it out easily at https://playground.prisma.io/examples
