Multiple return values

I've always found it weird that a function can take multiple arguments, but it can only return a single value. I guess you can make an Object array, and use that as a hacky workaround to return multiple values (of different data types instead of them all being the same, i.e. int[]).

What are your thoughts on having return values of different data types?

Functional programming apparently does away with return statements entirely, what's up with that?

Considering that every function takes a single argument

Then explain OOP?

so called multi-argument functions are simply nested functions

What? Are you thinking in terms of functional programming? I am coming from a mostly Java background.

How is this not a function with multiple arguments?
public string greeter(int age, string name) {
string message = "";
message += "Hello, ";
message += name;
message += "! You are "
message += age;
message += "years old!";
return message;
}
I know that's sloppy but I'm tired, but it clearly takes two arguments
