message: Include useBabelrc in react-native example
  As far as I know `useBabelrc` has to be set to true so that ts-jest uses the `.babelrc`. Since the react-native section declares a `.babelrc` it should also show that the option needs to be enabled.

  If only testing typescript files then remove the `js` option in the testRegex.
