Node.js to get/determine OS version

Question

I\'d like to determine whether some script that is being executed is running a particular version of Mac OSX. I realize I can exec/spawn the command:

sw_ver

As mentioned above in AndyD's answer's comments, os.release() returns the kernel version. If you want to get the same version number that a user sees in the "About this Mac" UI, you can read and parse out /System/Library/CoreServices/SystemVersion.plist, like so:

const plist = require('plist');
let versionInfo = plist.parseFileSync('/System/Library/CoreServices/SystemVersion.plist');
console.log(JSON.stringify(versionInfo));
