Hopefully this will be helpful to someone else as they’re working through at least the early lessons.
On linux, using “watch” + the lesson you are actively working on will constantly reload as you go, assuming you are saving every couple of lines. If you have a smaller terminal window open, it will allow you to quickly glance over and see if the line you just entered is throwing an error etc, vs. moving windows and typing the name in again.
Once you navigate to the directory you’re saving lessons to, enter " watch node exXYZ.js"
Default reloads every couple of seconds.
