Expo init command in CLI has only two options to create project. Blank project and something with React Navigation.
It would be nice, it there will be third option -> Typescript. It will create same project as blank one, but it will have tsconfig.json and some necessary things, which are required (and/or) useful. (For example, I don't know, if I need package tslib). Some Babel configuration, when TS is natively supported
