"Arrays": SugarCube (v2.18)
Arrays are a collection of values. Each value in an array is assigned an index, which is a number that corresponds to the position of that item or element. Arrays have many built-in methods and other features, and SugarCube adds many more. Arrays can be created by assigning a variable to the array literal, which is a pair of brackets (
<<set $myArray to >>.
Specific elements can be accessed in an array by following its variable name with a pair of brackets containing the index to check. Testing whether an array contains an element can be done using the Array#includes() function; adding new items can be done using the Array#push() function.
