Functions

func Every

func Every[T comparable](
	slice []T,
	predicate func(value T, index int, slice []T) bool,
) bool

Every returns true if all elements satisfy predicate.

• If at least one element does not satisfy predicate, false is returned.

func Filter

func Filter[T comparable](
	slice []T,
	predicate func(value T, index int, slice []T) bool,
) []T

Filter returns slice with elements that satisfy predicate.

• If slice is empty, slice is returned.

func Find

func Find[T comparable](
	slice []T,
	predicate func(value T, index int, slice []T) bool,
) T

Find returns first element that satisfies predicate.

• If element is not found, zero-value is returned.

func FindIndex

func FindIndex[T comparable](
	slice []T,
	predicate func(value T, index int, slice []T) bool,
) int

FindIndex returns first index of element that satisfies predicate.

• If index is not found, -1 is returned.

func FindLast

func FindLast[T comparable](
	slice []T,
	predicate func(value T, index int, slice []T) bool,
) T

FindLast returns last element that satisfies predicate.

• If element is not found, zero-value is returned.

func FindLastIndex

func FindLastIndex[T comparable](
	slice []T,
	predicate func(value T, index int, slice []T) bool,
) int

FindLastIndex returns last index of element that satisfies predicate.

• If index is not found, -1 is returned.

func Flat

func Flat[T comparable](slice [][]T) []T

Flat returns slice with sub-slices concatenated.

• If slice is empty, slice is returned.

func ForEach

func ForEach[T comparable](
	slice []T,
	predicate func(value T, index int, slice []T),
)

ForEach executes predicate on every element in slice.

• If slice is empty, predicate is not executed.

func Includes

func Includes[T comparable](slice []T, element T, fromIndex int) bool

Includes returns true if element is found in slice.

• If fromIndex is negative, it is set to 0.
• If fromIndex is greater than slice length, false is returned.
• If element is not found, false is returned.

func IndexOf

func IndexOf[T comparable](slice []T, element T, fromIndex int) int

IndexOf returns first index of element in slice.

• If fromIndex is negative, it is set to 0.
• If fromIndex is greater than slice length, -1 is returned.
• If element is not found, -1 is returned.

func LastIndexOf

func LastIndexOf[T comparable](slice []T, element T, fromIndex int) int

LastIndexOf returns last index of element in slice.

• If fromIndex is negative, it is set to 0.
• If fromIndex is greater than slice length, -1 is returned.
• If element is not found, -1 is returned.

func Map

func Map[T comparable](
	slice []T,
	predicate func(value T, index int, slice []T) T,
) []T

Map returns slice with elements after applying predicate.

• If slice is empty, slice is returned.

func Pop

func Pop[T comparable](slice []T) T

Pop returns last element of slice.

• If slice is empty, zero-value is returned.

func Push

func Push[T comparable](slice []T, elements ...T) []T

Push returns slice with elements added at end.

• If elements is empty, slice is returned.

func Reduce

func Reduce[T comparable, R comparable](
	slice []T,
	predicate func(accumulator R, value T, index int, slice []T) R,
	initial R,
) R

Reduce returns accumulator after applying predicate to each element.

• If slice is empty, initial is returned.

func Remove

func Remove[T comparable](slice []T, element T) []T

Remove returns slice without element.

• If element is not found, slice is returned.

func Shift

func Shift[T comparable](slice []T) T

Shift returns first element of slice.

• If slice is empty, zero-value is returned.

func Some

func Some[T comparable](
	slice []T,
	predicate func(value T, index int, slice []T) bool,
) bool

Some returns true if at least one element satisfies predicate.

• If no element satisfies predicate, false is returned.

func Splice

func Splice[T comparable](slice []T, start, deleteCount int, elements ...T) []T

Splice returns slice with elements added at start.

• If start is negative or greater than slice length, it is set to slice length.

• If deleteCount is greater than slice length minus start, it is set to slice length minus start.

func Unshift

func Unshift[T comparable](slice []T, elements ...T) []T

Unshift returns slice with elements added at start.

• If elements is empty, slice is returned.
