Functions

func Contains

func Contains[T comparable](slice []T, e T) bool

Contains returns true if a slice contains an element

func Map

func Map[T any, K comparable, V any](slice []T, fn func(T) (K, V)) map[K]V

Map takes a slice of a given type and a function to extract a map key and value from slice elements, returns a new map with those key-value pairs. Note that if multiple elements in the slice return the same key, the element that appears last in the slice will be the (only) element that maps to the key.

func Transform

func Transform[T any, V any](slice []T, fn func(T) V) []V

Transform takes a slice of a given type, and a function to perform on each element to transform it into a different type
