So real quick and simple, yes here it is:
It depends on the situation if you are calling your node script like this:
Then it is not at all important as you are directly calling node. It becomes important to use it when developing a stand alone Command Line Interface tool using node.
If you use formating or minification tools it can sometimes mess up the shebang, so if you are using one make sure that it leaves it alone.
I have written a newer post that covers in greater detail how to go about getting started making a CLI tool in node.js. Be sure to check that out if you want to learn more about how to make global scripts that you can call from anywhere within the Command Line Interface.
That’s it, this is a short post aimed at a very specific topic of interest. It is a relevant part of getting into what is needed to be understood when it comes to developing CLI tools with node.js, but that is a whole other ball of wax as I see it. When it comes to it I will link and and expand this post accordingly.
