|
The `strings.splitAfterN()` function splits a string after a specified separator and returns
|
|
an array of `i` substrings.
|
|
Split substrings include the separator `t`.
|
|
|
|
_**Output data type:** Array of strings_
|
|
|
|
```js
|
|
import "strings"
|
|
|
|
strings.splitAfterN(v: "a flux of foxes", t: " ", i: 3)
|
|
|
|
// returns ["a ", "flux ", "of foxes"]
|
|
```
|
|
|
|
## Parameters
|
|
|
|
### v {data-type="string"}
|
|
The string value to split.
|
|
|
|
### t {data-type="string"}
|
|
The string value that acts as the separator.
|
|
|
|
### i {data-type="int"}
|
|
The maximum number of split substrings to return.
|
|
`-1` returns all matching substrings.
|
|
The last substring is the unsplit remainder.
