Coding means creating programs that can run on computers or mobile devices. Through already developed tools, you can create simple programs even if you don't know difficult programming languages. Of course, you need to know programming languages, which are sometimes referred to as a third foreign language, to create more professional programs, right?

Also, there are many people who have a dream of becoming a developer, a field with a shortage of manpower now but a promising future. In such cases, it is necessary to learn basic coding and to determine your current level of skill and whether it suits your aptitude.
 
Of course, there are many YouTube tutorials. However, YouTube is difficult to find the right one, and it is not a good place for beginners to learn systematically. YouTube lectures are more suitable for those with intermediate or higher skills. Now, I will briefly introduce the sites that are currently in service and their characteristics. 
 

 
1. Try before you start: A collection of free online courses 

  
First of all, I recommend the site of Goin's Living Coding (Open Tutorials), which has been consistently providing service since 2012. The site is organized neatly, the explanation is friendly, it's free, and it's professional. You can learn the basics of web, databases, various programming languages, servers, and development tools. It has a cute taste, so it is a good service to learn step by step.

Second, I recommend the free courses of Khan Academy, which recently started services in Korea. 
 
Khan Academy is a global service created with the aim of providing world-class education for free to everyone, anywhere. It provides high-quality courses in JS, HTML/CSS and web page creation, SQL and advanced data querying and management, creating interactive web pages with jQuery, algorithms, cryptography, C++ programming, programming language theory, linear algebra, etc. It also provides various services such as elementary and middle school mathematics, US mathematics, and even free SAT practice problems, so you should refer to them.

It is an online/offline education provided by Software Play to enable anyone to learn software easily and enjoyably. Block coding that learns through play, unplugged without a computer! Unplugged, physical computing that I create myself, computer science that becomes more interesting the more you learn, and there are many very basic and fun lectures.

■ Entry https://playentry.org 
It is an Entry lecture where anyone can easily watch and follow it and create various fun and interesting software. It looks like a site made with elementary school coding education in mind.
 
■ Open University Online Course (KOCW) http://www.kocw.net/home/index.do 
KOCW is a service that provides free lecture videos and materials that have been voluntarily disclosed by universities and institutions in Korea and abroad. It is available to anyone, including college students, professors, and anyone who needs learning, anytime, anywhere. You can start taking the course immediately after joining as a member of the Integrated Academic Research Information Service. There are courses such as game engineering, multimedia, computer engineering, and computer science. Find a programming related course from among them and take it. 
 
■ Google Coding Program https://edu.google.com/code-with-google/   
If you can speak English, it would be good to take a course offered by Google. Select the desired course from the [Explore Code with Google programs] item at the bottom of the site, and you can start taking the course right away.

■ STEP Online Lifelong Education Institute https://step.or.kr/ 
It is a lifelong career development learning platform that anyone can use, created by the government. It encourages learning by holding various events. 

2. Let's learn properly by paying: A collection of paid online courses 

 
I feel like there are a lot of online coding education services these days. From the consumer's point of view, it is also advantageous because you can choose a good service among various services. Browse the sites below and take a good course. 
 
■ Code States https://www.codestates.com 
It is a paid site. As you know, it takes tens of millions of won to learn coding properly. ㅠㅠ However, a program is provided for those who can't afford to pay the tuition right away. It's a pre-payment, we win program. In other words, it is a method of paying after getting a job. Be careful that you will end up paying more than you think if you use this program. A certain percentage of your salary will be deducted. Make sure to check the details of the program before using it.

■ Infrlearn https://www.inflearn.com
