Ha, funny -- clicking that link leads to a page w/ this message: "This page is unavailable when linked to from news.ycombinator.com. Please find a less toxic place to spend your time." :-)
Yes, of course, re using TypeScript or Flow. However ... I'm not a fan of TypeScript -- if I'm going to use a different "language" (albeit one that's a transpile-able thin veneer over JS) I may as well switch to a language w/ an even better type system.
Flow, from the little I know, is closer to what I want -- still JS, but an annotation or "compilation switch" makes everything typecheck.
Thx. Hadn't looked at timelines, and assumed it was the other way. Great job w/ hyperapp. Congrats!
FWIW I like Elm, and hyperapp seems a delightful port of the TEA idea ... plus for being a js library, with immediate access to JS and DOM. I'll look for examples using 3rd party visual widgets, and animation libraries.
That said IMO TEA is only a convenience. What I find supremely empowering about Elm is its type inference/system. If we got that in JS-land I likely wouldn't look at another language for some time to come :)
The link works when copy/pasted. Let me read.
