Switching From NPM to Yarn

We've switched to Yarn because it was built in collaboration with Facebook, Google, and others. We're primarily using it for how much faster it is though. Yarn supports emojis, is extremely faster, has automatic shrinkwrapping (hence the yarn.lock file), and much better security.

You can find out why a package is installed (and what's using it):

yarn why <package-name>
