/** 1. Create a features.js script that has one method function calculateFeatures(tokenData) {...}. You will need this for Artblocks anywayz.
    2. Add this line to the bottom: export default calculateFeatures;
    3. Copy the contents of this gist into generate-features-json.js
    4. In your terminal, run node generate-features-json.js. 
    5. The script will take a minute to generate 2,000 outcomes and compile all of the different traits.
    6. Tada. features.json can be uploaded to Artblocks.

Setup Mac OS X

I've done the same process every couple years since 2013 (Mountain Lion, Mavericks, High Sierra, Catalina) and I updated the Gist each time I've done it.

I kinda regret for not using something like Boxen (or anything similar) to automate the process, but TBH I only actually needed to these steps once every couple years...
