As a workaround, you could consider some automatic mirroring software like Mirror Folders or AOMEI Backupper for PC.
I didn't find any kind of automatic app for this on macOS, but this command will create a synced JavascriptLibs folder in your documents folder.
rsync -va --delete "/Library/Application Support/TroikaTronix/JavascriptLibs/" ~/Documents/JavascriptLibs/
One nice way to automate this is to create an Automater script that runs at system startup
Open AutomatorChoose to create a new documentChoose the "Application" optionFrom the list of possible actions, choose "Run Shell Script"In the "Run Shell Script" Item that appears on the right, paste the rsync code from aboveSave the Automator workflow to your Documents folder as "backup-javascript-libs.app"Quit AutomatorGo to System Preferences > Users & Groups > Login ItemsClick the "+" button and enter your password if necessarySelect "backup-javascript-libs.app" from your documents folder and click Add
Now, every time you restart your computer, the JavascriptLibs is backed up to your Documents folder.
If you're comfortable with with a bit of low level stuff, you can go even further and schedule the rsync command to run periodically using cron. See this StackOverflow article for help on that.
Hope that helps,
