Type: String

A String is a sequence of characters.

10.2.1 Array.........................................

AnArrayis a collection of elements. It has one type parameter (3.2) which corresponds to the

type of these elements. Arrays can be created in three ways:

1.By using their constructor:new Array()

2.By using array declaration syntax (5.5):[1, 2, 3]

3.By using array comprehension (6.6):[for (i in 0...10) if (i % 2 == 0) i]

Arrays come with anAPIto cover most use-cases. Additionally they allow read and write

array access (5.8):

1 class Main {
2 static public function main() {
3 var a = [1, 2, 3];
4 trace(a[1]); // 2
5 a[1] = 1;
6 trace(a[1]); // 1
7 }
8 }

Since array access in Haxe is unbounded, i.e. it is guaranteed to not throw an exception, this

requires further discussion:

• If a read access is made on a non-existing index, a target-dependent value is returned.
