A while back, I demonstrated using Sizzy(affiliate link) to develop responsive websites. Today, I'm going to demonstrate some of the great new features in the latest release of Sizzy (console logging, filtering, etc).
NOTE: The links to Sizzy below are affiliate links. They were added on 12/31/2019 - several days after this post was written. I was then and still am a Sizzy customer and would recommend it to you regardless of any affiliate payments I might receive.
In addition, I demonstrate using Sizzy to debug and develop React Native apps in the browser using Expo for Web.
NOTE: If you just want to see a really quick example of using Sizzy and making changes in React Native code, watch the video from the 2:50 point.
