NodeJS and MongoDB. And tutorials.

Everywhere tutorials show simple example of console.log output of findOne. Good, that works... But when I try to extrapolate example to assign results to variable, it won't work. Inside that fetch anonymous function it works... But outside, simply undefined no matter what I try. Return doesn't return either...

Why it is so hard to make tutorials and examples that would be actually useful. I've spent hours with this already.

And on top of that it is really hard to find tutorials staying with minimum extra dependencies. Like most tutorials in this case throw mongoose in the soup. And I don't want that.

Sometimes makes me question why I try to learn these new things, when I have knowledge of other technologies that I could use faster and easier...
