Functions

func Filter

func Filter[S ~[]E, E any](s S, f func(int, E) bool) S

Filter returns a new slice containing only the elements in the input slice s for which the specified function f is true.

func Map

func Map[S ~[]E, E any, U any](s S, f func(int, E) U) []U

Map returns a new slice that contains each of the elements of the input slice s mutated by the specified function.

func Reduce

func Reduce[S ~[]E, E any, U any](s S, init U, f func(int, E, U) U) U

Reduce applies the reducing function f to each element of the input slice s, and returns the value of the last call to f. The first parameter of the reducing function f is initialized with init.
