12 Fundamentals of Functional Programming

Question 1

Define function type.

Question 2

Define co-domain and domain.

Answer 2

Domain is a set from which a function’s input values are chosen
Co-domain is the set from which the function’s output value is chosen.
A function is mapping from a set of inputs (domain) and set out outputs (co-domain)

Question 3

What is a first-class object and how is it used?

Answer 3

any object that can be passed as an argument to or can be returned by a function

Question 4

e.g. Haskell, Standard ML
Scheme
Lisp.
