What is Referential Transprency in Erlang

Question

Anonymous User · Answer

A function with the same parameter should always return the same result:

x = add_two_to(3) = 5
∴ x = 5

Functions always returning the same result for the same parameter is called referential transparency. It's what lets us replace add_two_to(3) with 5, as the result of 3+2 will always be 5.
