# toJS property

JSFloat64Array get toJS

Converts this Float64List to a JSFloat64Array by either casting, unwrapping, or cloning the Float64List.

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 Float64List is a wrapper around a `Float64Array` if it was converted via JSFloat64ArrayToFloat64List.toDart. If it is a wrapper, this getter unwraps it and returns the `Float64Array`. If it's instantiated in Dart, this getter clones this Float64List's values into a new JSFloat64Array.

Avoid assuming that modifications to this Float64List will affect the returned JSFloat64Array and vice versa on all compilers unless it was converted first via JSFloat64ArrayToFloat64List.toDart.

## Implementation

    external JSFloat64Array get toJS;
