I made use of a tool, nodemon, that would run your Node.js code and on detecting a change in the filesystem, would automatically restart your code...Node now has this built-in via a simple command-line flag: --watch.
Two things to note here - it cleared the entire terminal, which is useful, and gave useful messages about restarting and finishing. If my script took time to run, having that first message about restarting would be really useful.
