Doubt with ionic design generation

I have this environment installed:
Nodejs = node-v6.9.1-x86.msi
Npm = 3.10.8
Jdk = jdk1.8.0_91
Cordova = 6.4.0
Ionic = 2.1.13

When I enter cmd as administrator, I requested the creation of a project forcing ionic summer 2, I noticed that the folder structure is different and the extension of the files and “ts”, how could I have the version in “js”?

Ionic start nameApplication tabs --v2

o meu package.json e bem diferente

You can’t.

Ionic 2 and Angular 2 are made with Typescript (.ts) and not Javascript (.js)

Ionic with Javascript only v1
