tutorials/best_practices/scenes_versus_scripts

We've already covered how scenes and scripts are different. Scripts define an engine class extension with imperative code, scenes with declarative code. Each system's capabilities are different as ...

As a developer having almost little to no C++ experience I struggle to understand why Anonymous Types section is called as such.
ChatGPT suggest the following explanation: Creating a scene directly in script is like using anonymous types in programming: both involve dynamically defining structures without formal pre-defined templates or class names
Is this what is implied here?

thanks <3

It's Anonymous because it isn't defined or tied to an object/node, I think.

I honestly wouldn't worry about it.

The main purpose in the way I interpreted it is to differentiate from the "named types".
The named types basically lets you definite a node which you can then use in future scenes while the anonymous types only create those scenes at runtime.
Not a very good example, but I have a Custom Type made for my enemies which I can select in the editor as a baseline template to work off on..
However, if I'd like to spawn an enemy by creating a new enemy and instantiating it through a script, I would be making an Anonymous Type since the new enemy won't be saved anywhere (unless I specifically choose to have it).

I'm worried about the performance difference when using statements like Node.new() or add_child() in my Classes:

"Script code like this is much slower than engine-side C++ code. Each instruction makes a call to the scripting API which leads to many "lookups" on the back-end to find the logic to execute."

Isn't this how ALL Godot Scripts work? or is it only slower when using methods to add or edit instances?

I hope that the section is just recommending to use Scenes to create predefined node trees over manually creating nodes via Script.

I found that I was constantly worrying about performance until I started measuring things. How are you measuring your performance? What's your minimum spec target hardware and target frame time for that hardware? When you measure the performance difference between using scenes or using those statements, does it make a significant difference in your game?
