# toJS property

JSDataView get toJS

Converts this ByteData to a JSDataView by either casting, unwrapping, or cloning the ByteData.

Note

Depending on whether code is compiled to JavaScript or Wasm, this conversion will have different semantics.

When compiling to JavaScript, all typed lists are the equivalent JavaScript typed arrays, and therefore this getter simply casts.

When compiling to Wasm, this ByteData is a wrapper around a `DataView` if it was converted via JSDataViewToByteData.toDart. If it is a wrapper, this getter unwraps it and returns the `DataView`. If it's instantiated in Dart, this getter clones this ByteData's values into a new JSDataView.

Avoid assuming that modifications to this ByteData will affect the returned JSDataView and vice versa on all compilers unless it was first converted via JSDataViewToByteData.toDart.

## Implementation

    external JSDataView get toJS;
