### Array spreads

**Since 11.1**


You can spread arrays of the the same type into new arrays, just like in JavaScript:

<CodeTab labels={["ReScript", "JS Output"]}>

```res example
let y = [1, 2]
let x = [4, 5, ...y]
let x2 = [4, 5, ...y, 7, ...y]
let x3 = [...y]
```

```javascript
var Belt_Array = require("rescript/lib/js/belt_Array.js");

var y = [
1,
2
];

var x = Belt_Array.concatMany([
[
4,
5
],
y
]);

var x2 = Belt_Array.concatMany([
[
4,
5
],
y,
[7],
y
]);

var x3 = Belt_Array.concatMany([y]);
```
</CodeTab>

> Note that array spreads compiles to `Belt.Array.concatMany` right now. This is likely to change to native ES6 array spreads in the future.

## List

ReScript provides a singly linked list too. Lists are:
