Go 1.18 added generics to the language. This allows you to have your types take types as parameters so that you can create composite types (types out of types). This lets you get a lot of expressivity and clarity about how you use Go.
I assume the difference is that without generics you can't freely re-compose a struct type again with different, other types. You have to make a whole new struct type from scratch
The core difference is that structs are static. Once a struct is defined the type are fixed. "composite types" here refers to type that can be dynamically changed when you annotate them. i.e. if you have an custom array type, you can compose them on the fly with MyArray[int] or MyArray[MyCat], structs can't do that.
I don't normally care about the author's gender, but I'd argue assuming that is a man is a honest mistake, as long as women in the tech industry is still a minority. Do you really need to go that far? I think that shows how fragile you're.
