Computer Programming

This course is a comprehensive introduction to programming. It covers a wide range of topics, from basic syntax to advanced concepts. We have created these tutorials before AI was invented. It may not be perfect, but we have study hard to make this content accesible and easy to assimilate.


Anyone who wish to learn how to code is welcome to read and follow this course. We accept students, freelancers, mentors, engineers and professors who wish to learn how to code. This course is beginner friendly but you will have an advantage if you follow Software Engineering course first. If you don't you can watch the video below to get familiar with top programming languages.

This programming courses can help you learn the skills you need to become a peofessional coder. The course covers the essential syntax and semantic for various programming languages. Professional coders usually master 3 up to 5 programming languages but they are also familiar with main features of other top languages. There are many benefits for learning several programming languages:

As ChatGPT and AI continues to develop, it will become increasingly capable of performing tasks that are currently done by human programmers. Learning multiple programming languages will help you avoid becoming obsolete. Elite programmers will still be needed to design and implement new software applications, and to solve complex problems that AI cannot.


Our course contain tutorials for 21 popular programming languages. We advice for beginners to start with one of the simplest languages: Go, Julia, Dart or Python. More advanced developers, of course can chose whatever language they prefer. Selecting your first programming language is a difficult task. Read and watch the content below, to help you decide better.

Prep Quiz

For every language we provide one prep quiz that has 100 questions each. Next developer quiz is a fast general quiz you can take to learn how a prep quiz look like. If you score more than 80% at any of these quizzes you can claim the Sage-Code Developer role on Discord. Our quizzes are created with Google forms. You need a Google account to login before you start a quiz.
