This Google project for web developers launched in 2010 to counter Apple’s HTML5. The site is full of tutorials, resources and the latest HTML5 updates. It’s open source, so developers can play around with HTML5 code. Because this site's offerings are more advanced than most introductory courses, you'll need some knowledge and experience before jumping in.
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.
Luckily, institutions like the Flatiron School and The Grace Hopper Program offer scholarships or deferred tuition to make these bootcamps more affordable for under-represented groups like minorities and women in tech. Check out Course Report for a comprehensive breakdown of the many online and in-person bootcamps—including detailed reviews from their alums, which can help you decide whether a bootcamp is going to help you achieve your programming dreams.
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 less work your fingers do to press the keys the faster you will be able to move them. Most keyboards require only a light touch to register a key stroke, so there is no need to mash the keys down. You should type with the minimum force necessary. You will type faster and put less strain on your body. Typing involves muscles not only in your fingers, but in your hands, arms, back, shoulders, neck and head.

Second, measures your keystroke dynamics and collects comprehensive typing statistics. For example, it measures your typing speed for each individual key, and uses this data to generate random words putting emphasis on the weakest key. The more troubles you have with a particular key, the more you will be  typing it. It means, the generating algorithm will put that letter in every word in the next generated lesson. Your typing skills are re-evaluated after every completed lesson, and the next lesson will be adjusted accordingly.
AGupieWare is an independent app developer that surveyed computer-science programs from some of the leading institutions in the U.S. It then created a similar curriculum based on the free courses offered by Stanford, MIT, Carnegie Mellon, Berkeley and Columbia. The program was then broken into 15 courses: three introductory classes, seven core classes and five electives.
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.
