This is a simple Node.js application that displays the contents of a file containing JSON-encoded data on the left and the result of parsing that file using a Python script on the right. The latter is executed by the Node.js application as a spawned child process.
The GitHub repository for this Node.js application can be found at macos-versions.
The information on macOS (Mac OS X) releases contained in the file macos.json is for demonstration purposes. While every attempt has been made to ensure this data is correct, its accuracy is not guaranteed.
