How is your code sample for an object any different from a function definition?

In both cases you need to read the documentation, consult the source, or have an IDE that does.

That depends entirely on how the object is constructed. Plenty of implementations use object.new() and you’re expected to fill in the blanks.

Besides, even if you have a constructor that takes parameters, it’s essentially the same as calling a function. Get it wrong and stuff breaks.

Which bit isn’t possible?

As far as data types goes, you can apply the same logic to function parameters.

In my experience, naming the elements in an object requires exactly the same documentation as naming the elements in a function call and it makes things worse if you forget to assign a value to one of them, since the object constructor will likely assign an unknown default value.

With explanations like this, who can blame them 😁
