Good morning, I'm new to the world of node-red, I come from back-end programming with .netCore. I saw that inside node, you can use functions, so I would like to ask for tutorials, handouts, example scripts. Apparently the font is very similar to JavaScript, but I'd like to see more in depth on the subject.
Thanks.

The code in a `function` node is JavaScript. A function node is used when you can’t find an existing node that will do what you want.
I recommend watching this playlist: [Node-RED Essentials](https://www.youtube.com/playlist?list=PLyNBB9VCLmo1hyO-4fIZ08gqFcXBkHy-6). The videos are done by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in about 1 hour. A small investment for a lot of gain.

It is Javascript and here is some info on creating functions

There’s a typo on that page. I’m assuming they meant “arbitrary”
