2024-03-13 17:16:29 +00:00
var numbers = [0, 1, 2, 3]
2023-10-02 01:41:38 +00:00
2024-01-01 14:11:41 +00:00
numbers[3] = 5
2023-10-02 01:41:38 +00:00
2024-01-01 14:11:41 +00:00

## Type signature
```thp
Array[String]
Array[Int]
```
2024-01-01 14:11:41 +00:00
The Array signature __requires__ the word `Array`.
There is no `Int[]` or `[Int]` signature, since that would cause
problems with the language's grammar.
