CodePen: A JavaScript Console! [↗]
We have a JS console now! Hopefully it works exactly as you expect it to. As in, you can log things to the console and see the results, and you can type things into the console and see the results.
I’ve been loving CodePen, but due to its lack of console, I’d occasionally head over to JS Bin. I don’t need to do that any more, cool beans!
