But you’re not really starting from square one. Because really, deep down, you already know how to do it. Code is instructions. You write the instructions, and the computer follows them. Any time you’ve given someone directions to your house, or typed in a sum on a calculator, or lined up a row of dominoes, you’ve essentially been coding. The person following your directions, you pressing the equals button, knocking over the first domino - that’s the code being run. Coding is pretty much teaching a series of steps to a computer, for the sole reason that it can follow those steps a hell of a lot quicker than you can.
