With my exploration of OpenWhisk, I wanted to see if there was a more elegant way to solve this problem. The traditional approach would have been to simply make a request, handle the response in a callback function, make another request, handle the response in a nested callback function, and keep on nesting callbacks as deeply as necessity requires or sanity permits. I decided against the obvious solution and set out to write some code to find the answer. Thinking of my own GitHub repositories, I wondered how many would not have a license, and if there was an easy way to find out.

The unfortunate reality is that increasingly open source repositories are populated not by code carrying one of the aforementioned types of licenses, but no license at all. I came across a scenario like this just the other day when I read Stephen O’Grady’s blog post on the state of Open Source licensing. A familiar scenario for node.js developers: you want to make an HTTP request to a REST API, and depending on the response of the first request, you need to make more requests.
