`strings.splitN()` splits a string on a specified separator and returns an array of `i` substrings.

##### Function type signature

```js
(i: int, t: string, v: string) => [string]
```

For more information, see [Function type signatures](/flux/v0/function-type-signatures/).

## Parameters

### v

(Required) String value to split.

### t

(Required) String value that acts as the separator.

### i

(Required) Maximum number of split substrings to return.

`-1` returns all matching substrings. The last substring is the unsplit remainder.

## Examples

strings.splitN(v: "foo, bar, baz, quz", t: ", ", i: 3)// Returns ["foo", "bar", "baz, quz"]
