Use @Inject instead of static get parameters()

[mirkonasato]

Ionic 2 starter projects currently uses static get parameters() in esnext code as a workaround for the lack of parameter decorators in Babel. See e.g. Adding Pages in the tutorial.

Parameters decorators should now work using the babel-plugin-angular2-annotations: see shuhei/babel-plugin-angular2-annotations#19

So it should be possible to write

constructor(@Inject(NavController) nav, @Inject(NavParams) navParams) { /*...*/ }

Just noticed that the latest ionic-cli only supports typescript. So this doesn't matter any more.

@mirkonasato yeah! we took the decision to drop js support, since TS is a superset of JS it's up to developers to use the new features introduced.

This way we can concentrate our efforts of documentation, demos and testing.

@manucorporat good decision 👍

@manucorporat, what a shame that you guys took that decision.

TypeScript is simply too slow for me, so from the start I decided to use ES6.
I learned to write Angular 2 ES6 code using Ionic's templates. Not anywhere else in the web there was another starting point as good as Ionic.

And, to complete.. the official Angular docs are just poor in terms of ES6 support.
