Behold the "One HTML Page Challenge" -- to build a one-page site using just the code in a single html file: "Practice your skills with no assistance from libraries, no separation of files, and no assistance of a modern framework." There are a just few entries so far, but they're pretty cool -- like this one that creates a slowly-growing ant colony in ASCII, or this racing game, or this quiz to see if you can identify the correct name of a color. I dig the constraints here -- all code in one file, no outside code libraries -- because it really honors "view source" culture. When I was interviewing developers for my latest book Coders, all the ones who grew up during the late 90s and early 00s web talked about how powerful view-source was in teaching themselves to code and make stuff online. But web development these days has grown byzantine in its complexity; if newbie is trying to learn, view-source is liable to just cough up a slurry of incomprehensible, minified javascript.
