Array Type - Array<T>

The Array<T> data type is a unique data type, as it does not represent itself a value, but rather a sequence of multiple values. As a result of that an array has also a length and an index for each item, which you may use to access them using an bracket notation member access expression.

Generic Arguments

T

The generic argument T represents the type of the items that are stored in the array. Any other type not matching T will result in a type error.

Examples

Simple constant array definition

var var24: Array<num> = [2, 3, 4];

Accessing elements of an array

var var25: Array<num> = [2, 3, 4];
var item_of_list: num = var26[2]; // -> 4

Calling len function on an array

var len_of_list: num = len(var26); // -> 3

Calling last function on an array

var len_of_list: num = last(var26); // -> 4

Calling first function on an array

// ✓ Accessing the first item of the list using 'first()'
var len_of_list: num = first(var26); // -> 2

X May not set a list to a single value

var var26: Array<num> = 2;

X May not set item of list to an invalid type

var var27: Array<num> = ["string"];

X May not convert list to another type as a whole

var var28: Array<str> = ["99", "1893", "4"];
var var29: Array<num> = var27 as Array<num>; // -> Invalid conversion
