Codewars adds some quirk to the proceedings by offering free coding classes with a martial arts theme. Solving specific coding “katas” (a term for training exercises in karate) will earn you ranks and honors as you move your way to becoming a bonafide coder. Who said learning to code online couldn’t be fun? Codewars also offers one of the more diverse lists of programming languages. Choose free coding classes on:


Start small, but think big. Your project should involve skills you currently have in your toolbox, but you should also have a plan for future features and skills you’d need to turn that vision into reality. Without applying your coding skills in a few projects, you wouldn’t even be considered for professional coding gigs—so start planning and practicing. (Our advice? Use your coding chops to build an amazing setup for game night.)
Udemy bills itself as an online learning marketplace, hosting 130,000+ user-created courses on all kinds of topics (including over 2,000 coding-related classes). While some of Udemy’s offerings are paid (costing $20-$200 per course), there are plenty of free coding classes as well, including some shorter Tech 101-type courses that teach code for beginners.

The programming community is full of people who are willing to help the next generation of programmers. GitHub, the online hangout for developers who use Git to manage their coding projects, is designed for online collaboration. Not only do developers host and share their projects with their peers, they also provide code feedback and general advice to the community. 

The free typing lessons supply the complete "How to type" package. Animated keyboard layout and the typing tutor graphic hands are used to correct mis-typing by showing the right way to type for your learning and practice experience. Lessons' difficulty gradually raises as it starts from only 2 characters and ends with the entire keyboard. When the lesson ends, you can learn a lot from the practice trends: WPM, accuracy and errors distribution.
EdX is another leading online-learning platform that is open source instead of for-profit. It was founded by Harvard University and MIT in 2012, so you know that you’ll learn about cutting-edge technologies and theories. Today, edX includes 53 schools. You probably can’t go wrong with the free Introduction to Computer Science from Harvard University.

Instead, Keybr.com generates random, but readable and pronounceable words using the phonetic rules of your native language. These words look almost natural, and often they really are. Typing sensible text is much easier than repeating random letters, and it helps you to remember frequent key combinations. The latest point is very important. For example, it’s almost impossible for the letter ‘W’ to follow the ‘Z’ in English, and you will never type this combination in Keybr.com. Instead, you will type more common words, such as «the,» «that,» «with,» and so on. And soon you will learn how to type the «th» combo really fast.

Skillcrush’s Free Coding Camp is our totally beginner-friendly intro to tech, techies, and kick-ass careers that you can complete in less than five minutes a day. Delivered straight to your inbox, you will learn how to code in the simplest terms possible—and even get to try writing your own code!—so you can see if learning coding is the right move for you…
By recreating existing projects, you’ll learn more about the inner workings of your highly customizable device. You might even find yourself inspired to create new ways to use your mini-computer and delve further into the world of code. (You can even enroll in UC Irvine’s The Raspberry Pi Platform and Python Programming for the Raspberry Pi Platform class through Coursera, if you want a little help getting started.)
With your index fingers you can feel a bump on the keys 'F' and 'J'. When you type you must get back to these two keys as soon as a key has been pressed on the keyboard so that you know all the time where you are on the keyboard. If you don't find the keys 'F' and 'J' again you will get lost and make a lot of mistakes. For the same reasons the first lessons are done without ever moving your fingers from these two keys.
Created in 2006 by educator Salman Khan, Khan Academy is one of the original free online-learning institutions. With step-by-step video tutorials, you can  learn how to program drawings, animations and games using JavaScript and ProcessingJS, or learn how to create webpages with HTML and CSS. See, especially, Khan's "Hour of Code," designed to introduce students to one hour of computer science and computer programming.
