1. package install (in my case "typescript: "^3.2.2")
   - yarn add typescript
2. npm command register (if you installed typescript not global)
   - "script": { tsc": tsc" }
3. configure ts
   - (command) tsc --init
4. tsconfig.json

"compilerOptions": {
  "target": "es5",                  
  "module": "commonjs",
  "outDir": "./ts",
  "removeComments": true,
  "strict": true,
  "noImplicitAny": true,
  "esModuleInterop": true
}

6. tslint.json

{
  "extends": ["tslint:latest", "tslint-react"],
  "rules": {
    // override tslint-react rules here
    // "jsx-wrap-multiline": false
  }
}

5. further step for React-Native
- yarn add @babel/polyfill metro-react-native-babel-preset
- .babelrc -> preset -> metro-react-native-babel-preset
