Why learn programming? It's very interesting, well paid and requires only your computer to start! It may allow you to work remotely. The upcoming robotization will affect this field positively, unlike many others. Whatever profession you're into, odds are you will either do some coding yourself or depend on people doing it. So programming will remain both valuable and rewardable in the foreseeable future.


We do not provide theoretical content yet. If it's your first experience with Paqmind, please take a look at our How-to page to get yourself familiar with the approach.

The course is devoted to programming, studied on the basis of JavaScript language. We have chosen JavaScript not only because it's the most popular language in the world, it also has the widest application area (web, games, databases, robotics...) and it's simultaneously both simple and expressive enough to satisfy all our tutoring expectations.

Despite your probable expectations, we will use NodeJS instead of Browser. We believe that fundamental topics should be learned in isolation and to code in browsers you have to bother yourself with HTML, bundling, AJAX, asynchronicity, etc. – they just carry too much "extras".

We start with the most basic and universal things like: values, variables, booleans, functions, expressions, statements, conditions, loops and so on. Their knowledge is absolutely necessary to do anything in programming. Sometimes we will compare JavaScript to other languages to extend our context.

Our goal is to make the best timeless intro course for everyone who wants to learn programming. The target audience is totally not limited to future web developers. For the record, this course could be translated into Python, Java, whatever and most changes would concern only the syntax.

Whenever possible, we will avoid becoming trapped with special JavaScript features, quirks, and curious implementation details – there will be a separate course for that. Those who want to prepare themselves for the interview – look no further! However, if you are interested to finally learn what Programming is about – go on.
