Build Web Apps with Elm Workshop

This workshop uses the wonderful Ellie App for running Elm demos and exercises. Ellie is to Elm what JSBin or JSFiddle is to JavaScript.

All you need is a modern browser such as Chrome or Firefox. Verify your OS and browser can use Ellie by trying to compile this URL: https://ellie-app.com/TPL2qc9ca1/0. I've seen problems with some Linux distros in the past.

For more information and links to the demos and exercises we will use, visit https://github.com/jfairbank/elm-workshop.

The passengers, bounty hunter John Ruth and his fugitive Daisy Domergue, race towards the town of Red Rock where Ruth, known in these parts as The Hangman, will bring Domergue to justice. Along the road, they encounter two strangers: Major Marquis Warren, a black former union soldier turned infamous bounty hunter, and Chris Mannix, a southern renegade who claims to be the town's new Sheriff. Losing their lead on the blizzard, Ruth, Domergue, Warren and Mannix seek refuge at Minnie's Haberdashery, a stagecoach stopover on a mountain pass.
