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.
Codeasy is probably the newest one from the whole list. It is quite interesting educational course because it drives a new concept to computer science studying. You start learning there by reading an adventure story about fighting machines in the future. On your way, you’ll meet challenges that require real coding to solve. The final goal is to save the world from machine invasion. And as a very important side effect – become a software developer.
Once you figure out why you want to code, you can more easily pinpoint which programming language you should tackle. While there is no single “best” programming language to learn, some languages are more user-friendly than others. HTML and CSS are considered the easiest entry points into the coding world, but they are only really useful for developing basic websites.
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)!
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.
