Now here's the magic. If you just specify the name of a directory with no file name then node will automatically look for a file named index.js inside the specified folder:
The cool thing is that all of these commands will run the exact same file in the exact same way. Here's a super simple one-liner sample index.js file for you to try it out yourself!
