# toRange()

Converts the value to a range.

## Declaration

```swift
func toRange() -> NSRange
```

## Return Value

Return Value A range representation of the value.

## Discussion

Discussion This method treats the value as a JavaScript object, reading the values of its location and length properties using the toDouble() method and creating a NSRange structure from the result. If the value is not a JavaScript object or does not have the appropriate properties, the resulting range is invalid.
