Why I hate TypeScript
Warning: These views are highly oppinated and might have some slightly incorrect facts. My experience with typescript was about 2 weeks in Node and a week in angular2.
Its also worth noting that they have built some things like module system and as soon as the spec came out they ditched it and started using that. Have fun updating!
It should also be worth mentioning that this language has been around for a long time and only recently gotten popular because of Angular2.
Not Community Driven
There is no community really driving the language itself. From what I see, random new things end up there with little to no community feedback. I could be wrong here, but I just don't see it much.
Types in a non-typed language is hard
Its like trying to fit a square into a circle hole. A lot of the ES6/7 things I try to do don't work at all and will likely never work with the way some of the types work. I think it should be JS first and then types not the other way around.
Babel is way better
Babel is the ****! The plugin architecture system is amazing idea! I love being able to get community driven plugins ( Even if they might not be standard thats the risk I accept and am ok with ). I can target multiple environments ( node 4,5 / browser ). Plus, they are implementing specs and even if they are stage-0 and change, they are atleast some spec and i can run that plugin until I can update too.
I've been watching some of the targeting issues and they are pretty far out, TS on Node seems like a great fit, why not get that going asap?!
Babel is just SOOO far ahead ... The fact that people are using Babel and TypeScript together is a huge flag that TS needs to up their game.
Um, why do I need to mock fake TSDs for things that aren't TypeScript!? Your creating more headache, work, etc. This should have been addressed in v0!
No idea what language features I can use
I hit this all the time, I had no idea what ES* features I could use and what I couldn't. I spoke about this on a issue and they said they are only doing stage-3 but they have other things that are stage-0?
I think I've heard about 100x you can use as much or as little of it you want. Ya, good luck. Having to put
any everywhere is not my idea of that statement.
What about flow?
I do generally like the approach FlowType is taking.. they put JS first and then lay types on top. Also, I can use babel to compile it and its not as much of a plunge into a java/c# like language.
TS and Babel are doing similar type declaration syntax so its a safer bet that might be included in a upcoming spec and if it doesn't you can always use
