SLR25 Functional programming paradigms

Question 1

Domain

Answer 1

“A set form which a function’s input values are chosen.”

Question 2

Co-domain

Answer 2

“A set from which the function’s output values are chosen. Not all need to be outputs.”

Question 3

First-class object

Answer 3

“Objects which may: 1) appear in expressions 2) be assigned to a variable 3) be assigned as arguments 4) be returned in function calls.”

Question 4

Function application

Answer 4

“The process of giving particular inputs to a function.”

Question 5

Partial function application

Answer 5

“The process of fixing several arguments to a function, producing another function which has a smaller number of arguments.”

Question 6

Composition of functions

Answer 6

“The process of applying one function to the results of another.”

Question 7

Higher-order functions

Answer 7

“A function that takes a function as an argument, returns a function as a result or does both.”

Question 8

Map

Answer 8

“The name of a higher-order function that applies a given function to each element of a list, returning a list of results.”

Question 9

Filter

Answer 9

“The name of a higher-order function that processes a data structure, typically a list, in some order to produce a new data structure containing exactly those elements of the original data structure that match a given condition.”

Question 10

Reduce or fold

Answer 10

“The name of a higher-order function which reduces a list of values to a single value by repeatedly applying a combining function to the list values.”

Question 11

“A set form which a function’s input values are chosen.”
