 /**
  * Converts a Dart value into a JavaScript SerializedScriptValue.  Returns the

  * The main transformation is the translation of Dart Maps are converted to
  * JavaScript Objects.
  *
  * The algorithm is essentially a dry-run of the structured clone algorithm
  * described at
  * http://www.whatwg.org/specs/web-apps/current-work/multipage/common-dom-interfaces.html#structured-clone
  * https://www.khronos.org/registry/typedarray/specs/latest/#9

  * Since the result of this function is expected to be passed only to JavaScript
  * operations that perform the structured clone algorithm which does not mutate
  * its output, the result may share structure with the input [value].
