## Examples

### Basic Split

{
  "$split": [
    "apple,banana,orange",
    ","
  ]
}
```

Result: `["apple", "banana", "orange"]`

### Split by Space

```json theme={null}
{
  "$split": [
    "Hello World Test",
    " "
  ]
}
```

Result: `["Hello", "World", "Test"]`

### Field Value

{
  "$split": [
    {
      "$input": "tags"
    },
    ","
  ]
}
```
