This is fun stuff; other sites in the same vein include jsbin and jsfiddle. (You don't need processing; JavaScript + canvas pretty much covers it.) I think this is the "Apple II" of the current decade. JavaScript + HTML5 is pretty much everywhere, on tablets, phones, computers, all browsers, even on the server. Anyone can throw together a 20-30 line program that does fun things and share it with their friends, and run it anywhere. For all the attention the Raspberry Pi gets, I think this, JS + HTML5, is where kids and adults should be playing with programming. It's immediate, it's powerful, it's fast, it's ubiquitous. Only the most minimal IDE needed; very little boilerplate; a dynamic language with introspection, a read-eval-print loop is trivial and built in to most browsers, and on and on. I'm going to go so far as to make this prophecy: most hobby robots will be programmed in *JavaScript* in just a few years. -tom On Mon, Sep 10, 2012 at 2:39 PM, Mike Stay <metaweta@gmail.com> wrote:
Khan Academy recently released a JavaScript + Processing.js integrated development environment for teaching kids to program. It's a lot of fun. Here are a bunch of very simple demos I've written in the past week or so.
