Just a quick Github update. I upgraded superCell to all the latest packages as well as uploaded a few older starter builds for those interested. One that might be of interest was an advanced Webpack setup (dustDevil) for React I did last year I planned for a new YouTube series. It includes Hot Module Reloading, …

This algorithm did not come from a challenge but instead from a project I was working on. I had an array of objects that had to be filtered with another array…
