# cons(A, List[B]): List[A|B]
Inserts element to the beginning of the list.
cons(head:T, tail: List[T]): List[T]
# Parameters
| Parameter | Description |
|---|---|
head: T | Element |
tail: List[T] | List |
# Examples
cons("Ride", ["on", "Waves"]) # Returns ["Ride", "on", "Waves"]
cons(1, [2, 3, 4, 5]) # Returns [1, 2, 3, 4, 5]
# containsElement(List[T], T): Boolean
Check if the element is in the list.
containsElement(list: List[T], element: T): Boolean
# Parameters
| Parameter | Description |
|---|---|
list: List[T] | List |
element: T | Element to search for |
# getElement(List[T], Int): T
Gets the element from the list by index. getElement(arr, i) is equivalent to arr[i].
getElement(arr: List[T], pos: Int): T
# Parameters
| Parameter | Description |
|---|---|
arr: List[T] | List |
pos: Int | Index of the element |
# Examples
getElement(["Ride", "on", "Waves"], 0) # Returns "Ride"
getElement([false, true], 1) # Returns true
# indexOf(List[T], T): Int|Unit
Returns the index of the first occurrence of the element in the list or unit if the element is missing.
indexOf(list: List[T], element: T): Int|Unit
# Parameters
| Parameter | Description |
|---|---|
list: List[T] | List |
element: T | Element to locate |
# Example
let stringList = ["a","b","a","c"]
indexOf("a", stringList) # Returns 0
# lastIndexOf(List[T], T): Int|Unit
Returns the index of the last occurrence of the element in the list or unit if the element is missing.
lastIndexOf(list: List[T], element: T): Int|Unit
# Parameters
| Parameter | Description |
|---|---|
list: List[T] | List |
element: T | Element to locate |
# Example
let stringList = ["a","b","a","c"]
lastIndexOf("a", stringList) # Returns 2
# max(List[Int]): Int
