Numbers in Haskell are typed of course. They also exist as instances of a numeric typeclass hierarchy. I was confused with converting and working with numbers of different types, and not being sure which functions were polymorphic and could work with different numeric types. So I created a little diagram. Do note that the typeclass hierarchy of Haskell actually does somewhat follow the hierarchy of numbers in Math.

While this gist has been shared and followed for years, I regret not giving more background. It was originally a gist for the engineering org I was in, not a "general suggestion" for any React app.
Typically I avoid folders altogether. Heck, I even avoid new files. If I can build an app with one 2000 line file I will. New files and folders are a pain.
Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
$ python -m SimpleHTTPServer 8000
