# Arrays
Use square brackets as usual.
## Usage
```thp
val fruits = ["apple", "banana", "cherry"]
val apple = fruits[0]
print(apple)
val mut numbers = [0, 1, 2, 3]
numbers[3] = 5
print(numbers[3]) // 5
```
## Type signature
```thp
Array[String]
Array[Int]
```
The Array signature __requires__ the word `Array`.
There is no `Int[]` or `[Int]` signature, since that would cause
problems with the language's grammar.
