Let’s run the Elm code for our home page on Ellie. Copy everything in the
src/HomePage.elm file and paste it in the Elm area. Now copy the contents of the
beginning-elm/index.html file and paste it in the HTML area. After that, click the compile button. You should see our home page on the right side.
Ellie is good for trying a one-off experimental code. In addition to running simple programs, Ellie allows us to add Elm packages, work through compiler errors, and share our code with others. As of this writing, Ellie doesn’t provide a robust environment required for professional web application development. Hopefully, someday it will.
