This was one of my first programs—it was something like K equals grab the next char. Then I said if K equals “a”, print “a”; if K is “b”, print “b”. I pretty much did every letter, number, and some punctuation. Then at one point I was like, “Wait, I could just say, 'Print the variable!'” and I replaced 40 lines of code with one. I was like, “Holy shit, that was awesome!” That was some major abstraction for a six-year-old.
