HMR doesn't work

[AleksandrChernyavenko]

create new empty project, enable hot reloading, change text in App.tsx -> nothing happens

Expected result: text on screen should change

• create-react-native-app my-app --scripts-version=react-native-scripts-ts:
• cd my-app:
• npm start:
• press I ( open IOS emulator )

This fixed it for me:

tsconfig.json

 {
   "compilerOptions": {
-    "target": "es5",
+    "target": "es2015",
-    "jsx": "react-native",
+    "jsx": "react",
 ...

I'm wondering what the jsx option really does 🤔

Anyhow, if it works for you, it should be harmless. Do you want to create a PR to fix it?
