title: How to not show warnings in Create React App
body: <p>I'm using create-react-app from Facebook, when it starts via 'npm start' it shows me a list of warnings, such as:</p>
  
  <p>'Bla' is defined but never used<br>
  Expected '===' and instead saw '==' </p>
  
  <p>I don't want to see any of these warnings, is there a way to supress them? </p>
