Core Principles interview questions

1. A.a routine whose output depends only on its arguments and which causes no observable side effects
2. B.the property that an expression can be replaced by its resulting value without changing the program's behavior
3. C.the practice of never changing a value after it is created, producing new values instead of altering existing ones
4. D.a way of programming that describes what result is wanted rather than the step-by-step instructions to compute it

Answer + AI explanation with Pro

1. A.Declarative style
2. B.Referential transparency
3. C.Side effect
4. D.Pure function

Answer + AI explanation with Pro

1. A.Pure function — any interaction with the outside world or mutation of external state that a computation performs beyond returning a value
2. B.Pure function — a way of programming that specifies an explicit sequence of statements that change program state to reach a result
3. C.Pure function — a routine whose output depends only on its arguments and which causes no observable side effects
4. D.Pure function — the practice of never changing a value after it is created, producing new values instead of altering existing ones
