Explicitly state whether TypeScript development is supported

[ikoevska]

From Vladimir Amiorkov via email:

All of the examples I saw in both nativescript-vue and the playground were written in pure JavaScript. Our Pro UI plugin is entirely written in TypeScript which made it hard to choose what to use and was wondering if TypeScript should and could be used at all.
Suggestion: If TypeScript is either supported or not, mention it somewhere. I am not 100% sure if the VueJS developers expect to see JS or TS but from a perspective of a plugin developer I could go either way and I would like to know if there are any limitations to either approach.

Tasks:

• Explicitly state whether development using TS is supported. It seems to be a preferred path for {N} developers and the lack of information might be misleading.
• Note any troubleshooting info, quirks, or other very specific information related to TypeScript development in the {N}+Vue context.

Something I'd be interested in knowing too.. 😺
