Shortcut to render the first page of commits from a public GitHub repo

index.js

// Execute this code snippet in the browser console when you're
// already on a repo's webpage. This is pretty helpful when you
// want to read a large OSS project but feel overwhelmed or not
// sure where to start - this is a neat hack to take you to see
// the original core concepts of the project, which might not
// always work but does the job most of the time.
