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.)

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.

Your answer can help determine which programming language(s) you should master, as well as what sort of commitment (in time and money) your goal may require. For example, if your dream is to create the next great operating system or a killer alternative to PhotoShop , you would benefit from a formal computer science education that teaches you C++, as well as more complex topics like data structure, algorithms and memory allocation.

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.
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: 

What an incredible app. I’m so impressed. This company deserves loads of money to be thrown at it for making it free. My son has just switched from a Cambridge school to an American School and missed a lot of work. I think we were both about to give up. I didn’t know where to start to help him and being his new school is completely iPad based we felt deep despair at just the thought of trying to navigate through classrooms codes and half working text book apps. Now it’s all here in one place! Simple well explained and the practice really gets your confidence going. He had some maths homework and instead of the total melt down we both would have had trying to work out what was going on we flew through it!! THANK YOU! I love the fact that all the grades are here too so if there is a concept he is struggling with we can go back in the grades to see where that was introduced and work through it! We have been struggling for months trying to find the answer on line. It was only due to the fact that Khan kept coming up that I googled it and found the app. I truly pray this company gets loads of financial support to keep this app going! THANK YOU THANK YOU THANK YOU!!
Third, lets you introduce as few keys as possible to the lesson, adding more keys automatically when it decides that you are proficient at the current level. When you only start learning it generates lessons with words from a very small alphabet of the most frequent letters. When your typing speed for every key in that alphabet reaches certain threshold, the algorithm adds the next most frequent letter to the alphabet. And so on, until the next letter. This way you will learn the most frequent letters first, and the least frequent ones later. 

Learn using videos, interactive exercises, and in-depth articles in math (arithmetic, pre-algebra, algebra, geometry, trigonometry, statistics, calculus, linear algebra), science (biology, chemistry, physics), economics (microeconomics, macroeconomics), humanities (art history, civics, finance, US history, US government and politics, world history), and more (including computer science principles)!
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.
Khan Academy is a 501(c)(3) nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere.

The Khan Academy Kids team is a passionate group of engineers, artists, designers, and educators who joined Khan Academy from Duck Duck Moose, a maker of popular educational apps for kids. Khan Academy Kids is 100% free without ads or subscriptions.
The typing lessons of TypeLift are not just static content. Every time you start a typing practice the lessons are assembled dynamically to increase your learning effect and to avoid memorizing frequently practiced exercises. On top of that our smart error analysis repeats frequent mistakes while you practice to make your individual training even more efficient.
I recommend checking out CS Dojo, TheNetNinja, and Harvard’s CS50 YouTube channel. If you don’t have time to search for a perfect coding video or channel, you can also check out LinkedIn Learning’s vast video library for vetted and professional-looking tutorials. While the service’s $30/month subscription fee is nothing to sneeze at, you can binge-watch an unlimited amount of content and topics—making LinkedIn Learning a better deal than other on-demand online classes that come with annoying restrictions.
Also, something that I've found is that if you go wrong somewhere instead of mindlessly searching for the error (assuming there are multiple or you don't know the error's location) just start from the beginning and go down seeing that if this works. If you see a break and something disconnects, in all probability that's where the error is. It's all logic.
Based out of New Zealand, Code Avengers provides fun and interactive programming lessons for kids 5 to 14; for schoolteachers wanting to teach coding; for people going into coding professionally; and for creators ages 15 and up. Also offered are one- to three-day "code camps" for students up to 17. These day camps are located in multiple states -- and foreign countries.
