Anyone has Dart vs TS comparison ?
I'm heavy Dart user - interested hearing someone having experience in both.
- As of now, TS and JS result in faster pages for me, because with TS and JS I can use React.js instead of Angular or Angular-Dart, and render the pages server side. And TS + React is for me easier to make it run fast, also after page load.
- Dart makes the fastest browser faster (except on initial page load, see above), but other browsers slow down, because they need to download the Dart runtime. This tradeoff feels like a not-a-good-idea, at least not for the homepage and other pages that should load in an instant for new users. So I wouldn't be able to use Dart everywhere? And then I'd have to use both Dart and TS/JS = too complicated.
Minor things:
- I think I felt a bit annoyed that Dart only made warnings of things that I would have wanted to be compilation time errors.
- I like TS better, it looks a bit more like Scala with the `: Type` annotations.
- Dart didn't work well in Firefox for me, it felt like boring to try to investigate what was wrong. (This was in November 2013 perhaps.)
The things I don't like about TS, is that it takes long to compile. And that it takes a while to learn how to use it — I still don't know much about it actually. And I haven't found any good free TS editor on Linux. (I'm about to try Atom I think.)
If it's okay, I'd be interested in having a look at your Dart project? After all I spent fairly much time with Dart; it would be interesting to see what other people build with it :-)
My Dart thingy is commercial NDA bla bla bla - so the only thing I can say it's more than 20K LOC. I was always afraid that such a big app couldn't be mantained in lang without proper IDE on non-windows (for Dart I'm using Dart's team Eclipse plugin and/or Webstorm plugin).
In my case I'm just too lazy to code in lang without lexical this and as I understand JS is TS subset, so you still can shot yourself in the foot really easy, also from what I hear JS/TS is better suited for small projects whereas Dart shines when project gets bigger (tree shaking, proper SDK) and perf really matters. On the con side: I would love Dart had as good IDE/plugin as TS has on Windows (Visual Studio).
Or is it an internal in-company application?
Do you happen to know how many kb JS code gets downloaded to a browser that doesn't support Dart natively?
(Unless this is too classified :-) )
Yes weird things happens sometimes with JS... a little bit more often with JS than with TS I think because TS is more restrictive.
Full stack Dart seems like a good alternative. I wonder how popular it'll become now when there's Rust, Go and Scala.js too :-)
