Functions

func Abs

func Abs[T constraints.Integer](value T) T

Abs returns the absolute value of an integer

func Filter

func Filter[T any](ts []T, f func(T) bool) []T

Filter a list, return only elements that return true for the compare method.

func Map

func Map[T, U any](ts []T, f func(T) U) []U

Map returns a list of elements, where the new element is the result of running the passed function.
