CLUSTER MULTI THREADED NODEJS -- Run threads in parallel to speed up long processes

My JavaScript that creates thumbnails for hundreds of files is taking too long. So I have decided to speed things up with cluster.fork() that is built into Node.js. This will allow the workload to be spread out across my multi-core processor system.

⚠ 8:53 should read: index % forks === cluster.worker.id - 1

To follow along, you can fork this repository. I have added a tag you can check out that will bring you right to the point this video was created.
