A while back Jim documented the one weird trick that got JET working on JSFiddle via RawGit, which is a pseudo-CDN we can use until JET is published to a proper CDN. Also, take a look at Cliff’s work on CodePen in case you prefer that service.
My v2.1.0 JSFiddle base is embedded below. You’ll see I’ve updated the JS tab using the Migrating a v2.0.x Web Application to v2.1.0 instructions. Also, I found that you can move the
requirejs.config() block down to the bottom and it will still work–this seems to draw more attention to your example viewModel code and less to the frameworks.
