TODO

• Support platform file extensions, at first just by assuming iOS.
• Feed tsc file contents from memory, instead of having to persist to disk first.
• Make warnings from jscodeshift & flow-to-ts show up.
• Comments do not take inserted import typeof lines of code into account, see e.g. this file.
• Make nominal types, in order to not inline all properties in declarations:
  • Libraries/Components/View/ViewPropTypes.js
  • Libraries/Components/TextInput/TextInput.js ?
  • Libraries/StyleSheet/StyleSheetTypes.js
