"Tomorrow begins the hour of code!"
At first I was confused, but this 'hour of code' seemed to be a very exciting project. And now I'm all the way through Khan Academy's hour of code and finished the Frozen version of coding at www.code.org.
These blocks help you understand the basic working methods of coding, like repeating an act forever or making things happen at different circumstances. But the colorful puzzle pieces are not used by programmers, of course. They use lines of orders and numbers that might look like error pages.
I'm going to keep practicing coding so that I can make the mole a realistic body! Maybe sometime later I might be able to make it move.
