So appending '--typescript' is troublesome and not obvious? Like this?
react-native init AppName --typescript
That's it. I never knew in 2019 that adding an extra flag would be 'troublesome'. The description of your installation of a React Native and TypeScript project in 2018+ is greatly exaggerated.
Is the flag generating a project that works without anymore tweaking/setting up? If so, my reference to the blog is not accurate.
Also, a better reply would be “oh that article is not accurate anymore, now everything is setup for you I’d you add this flag!”
