Array

A built-in data structure that holds a sequence of elements.

Description

An array data structure that can contain a sequence of elements of any type. Elements are accessed by a numerical index starting at 0. Negative indices are used to count from the back (-1 is the last element, -2 is the second to last, etc.).

Example:

var array = ["One", 2, 3, "Four"]
print(array[0]) # One.
print(array[2]) # 3.
print(array[-1]) # Four.
array[2] = "Three"
print(array[-2]) # Three.

Arrays can be concatenated using the + operator:

var array1 = ["One", 2]
var array2 = [3, "Four"]
print(array1 + array2) # ["One", 2, 3, "Four&qu
