unsafeDeleteAt :: forall a. Partial => Int -> Array a -> Array a

Delete the element at index i in an array

unsafePartial $ unsafeDeleteAt 1 ["a", "b", "c"] = ["a", "c"]

unsafeInsertAt :: forall a. Partial => Int -> a -> Array a -> Array a

Insert the element at index i in an array

unsafePartial $ unsafeInsertAt 1 "b" ["a", "c"] = ["a", "b", "c"]

unsafeInsertArray :: forall a. Partial => Int -> Array a -> Array a -> Array a

Insert an array into another array at the given position.

unsafeInsertArray 2 [21,22] [1,2,3,4,5] == [1,2,21,22,3,4,5]

unsafeUpdateAt :: forall a. Partial => Int -> a -> Array a -> Array a

Overwrite the element at index i in an array

unsafePartial $ unsafeUpdateAt 1 "e" ["a", "b", "c"] = ["a", "e", "c"]

unsafeModifyAt :: forall a. Partial => Int -> (a -> a) -> Array a -> Array a

Overwrite the element at index i in an array

unsafePartial $ unsafeModifyAt 1 (\a -> a <> "e") ["a", "b", "c"] = ["a", "be", "c"]

unsafeHead :: forall a. Array a -> a

Get the first element in an array. Passing Nothing to unsafeHead will throw an error at runtime.
