Please don't. The last code can be small but is very difficult to be readen fast by anyone. Come back to that code in 3 months from now and you will see that you will need a couple of seconds to understand it.

The code must be easy to follow. The first refactor with async/await is perfect, stick with it.

Yes, I totally agree that #3 is difficult to read even for experienced JavaScript coders. I was just trying to give an example of how sometimes it's possible to condense code to just one line JavaScript. I am going through this tutorial on MERN full-stack by Stephen Grider and came across this.
