Elm (software): an interactive mail system Elm (physical): a tree Elm (this): "functional" software. While I do Knot No the language, any language which claims to be functional, but stateful behavior (such as network timeouts) is really not functional. AKA, pitching pretty/current buzzwords, rather than being a new/useful language.

As for a "useful SPA" - a useful SPA has at least 300 gal. capacity and seating for 4+.

Sigh - arbitrarily re-using names for pre-existing widgets is silly. Sort like claiming that Kleenex is actually a machine tool.
