I didn't get this! We have to build an object which is an instance of a class and that's the object of a class! How is that a function of a class is the object of that class?

You can pass a function as an argument to another function, much like passing an object to a function.
You can have a function return another function, just like a function returning an object.
Just like objects, functions can have attributes.

229,732 PointsI'm not sure you're using the correct terminology. Do you perhaps mean that the "function is a method of the class"?
Or are you talking about where a "function is a first-class object"?

The quote should be "Another part that's important about all of this process is that functions are known as first-class citizens or first-class objects."
The quality term first-class has nothing to do with the term
classwhich is an object type.
