The specialty of a programmer has been one of the most demanded for many years. We associate it first of all with a stable and high income, so many regret it: "Oh, I should have studied to be a programmer!" And at the same time, many forget that it is never too late to study, and if we got an interest in programming after graduating from university in a completely different specialty, this does not mean that we will not learn anything.

Yes, a second higher education is expensive. But fortunately we have the internet. And on the Internet there are many excellent portals with online courses, including programming. We will tell you about some of them today.

Of course, not all online platforms are mentioned here. If you use other training portals, do not hesitate to share them in the comments. For now, let's present our list.

So let's go:

CodeAcademy

• Level: beginner
• Course language: english
• What are taught: JavaScript, Python, PHP, jQuery, JavaScript, HTML, etc.

https://www.codecademy.com

The portal, which opened in 2011, has already registered more than 24 million users. The site will be useful for those who want to get basic programming skills. On the portal you can take language courses for free Python,PHP,jQuery,JavaScript,CSS,Htmland others. Here you can learn how to write simple programs and create your own websites. The site has a user-friendly interface, and you can register here in just two clicks. Each course is divided into several sections, divided into exercises, with explanations on the left and a field on the right where you must enter the code. The system remembers your progress, so you can continue exercising at any time you like. In addition, you can see what percentage of the course you have already completed. You can take an unlimited number of courses at the same time. The only problem is that somehow you have to remember all this - so we recommend that you take courses in turn, and not all at once.

• Pros: visibility, the ability to immediately see the result, a minimum of boring theory
• Minuses:not identified

CodeCombat

• Profile: programming
• Level: beginner
• Course language: English, Russian, French, Spanish, etc.
• What are taught: JavaScript

https://codecombat.com

Who said that programming is boring codes and nothing else? The authors of the CodeCombat project refute this stereotype and offer everyone to learn the language for free JavaScriptplaying. You will need to choose a character for yourself who has to go through an entertaining quest, and write a set of commands so that he can move through the maze. Hints will be displayed on the right side of the screen so you play and learn to code at the same time. In order to start the game, it is not necessary to register, but it is advisable. By the way, the participants themselves can contribute to the development of the project: for example, help with the translation of the site or offer their tasks for the quest.

• Pros: interactivity, clarity, simplicity
• Minuses:only one programming language

Kirienko on the basics of the popular Python programming language. Python is considered one of the most understandable and at the same time useful programming languages, so it is the experts who advise you to study it first. The course consists of 16 lessons, most of which contain video lectures, theoretical material and tasks. The materials will be useful not only for schoolchildren, but also for all those who want to seriously start learning programming.

• pros: a very detailed course with a maximum of explanations in Russian

In our age of technological progress, there is nothing surprising in the fact that many valuable and important knowledge can be found in the public domain. This also applies to knowledge in such an area as programming, which is now becoming an increasingly popular activity in the labor market. You can become a programmer without having a lot of money in your pocket.

What online platforms in the world provide the opportunity for free training in programming courses.

Created by professors at Stanford University in 2012, this platform is one of the most popular in the field of online education today. Courses are held free of charge in several languages, including Russian, but obtaining a certificate of passing some of them is only paid.
