what other code it’s dependent upon to use it

[Pink_Flower]

Abstraction -- In order to use a function, you only need to know its name, inputs, outputs, and where it lives. You don’t need to know how it works, or what other code it’s dependent upon to use it. This lowers the amount of knowledge required to use other people’s code (including everything in the standard library).

Does the first "it" refer to "a function"? How about the second "it"?
