Did they really create so many Zero-Touch nodes just for the sake of having custom-named inputs and outputs or how did they achieve this? As you can see, these are not custom nodes. And if they used Zero-Touch Nodes: Isn’t it a hell lot of work for such simple mathematical operations?
This is the name of the output. This is not a line of code as there is no “;” at the end.
At leat I don’t know of a function where you can hide “;” in statements. The line number can be turned off yes, but I haven’t found something similar for “;”
There is also a lacing mark at the bottom and there is a level selector in the input ports. Both indicate that this is no Code Block but a custom node.
It is not that hard to create so many nodes. If formulas are known in a text file or Excel sheet then you can write a script to autogenerate every node you need. Looking at the names of the ports it is probably from an automated process.
