Steps To Reproduce

Provide a detailed list of steps that reproduce the issue.

1. Create a new react native project
2. Open the starter code from any editor, i use VScode.
3. Go to App.js and scroll to line 27.
4. Hold on a little bit then the error would occur.

Expected Results

Since it is a starter code from the react-native team, which helps new developers to understand the codebase and how it works, that error should not be there. It can scare a new developer coming into ReactNative.
