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.
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.
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.
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.
