Pure function
Program function without side effects and which returns identical values for identical arguments / From Wikipedia, the free encyclopedia
In computer programming, a pure function is a function that has the following properties:[1][2]
- the function return values are identical for identical arguments (no variation with local static variables, non-local variables, mutable reference arguments or input streams, i.e., referential transparency), and
- the function has no side effects (no mutation of local static variables, non-local variables, mutable reference arguments or input/output streams).
