This HTML file will load the UI, if your code compiles andthe UI has been packaged
To package the ui, scala --power package .
or scala-cli --power package .
(and then refresh this page).
Note that if it won't compile, it won't package.
From the browser's console (in Developer Tools), you can see the output of printlns if you insert debugging statements. However, as the Scala is cross-compiled to JavaScript to run, the debugger won't be so useful.
See README.md for instructions for the assignment
