    Returns a new JS object in \a env with the properties of \a jsonObject,

    and leaving no exception pending, if a JS exception is raised during the

/*!
    Returns the enumerable properties of the JS object \a jsObject in \a env
    as a QJsonObject. Booleans, numbers and strings become JSON values of the
    same kind, nested objects and arrays become JSON objects and arrays, and
    JS \c null becomes JSON null. Property values with no JSON counterpart
    (\c undefined, functions, symbols, \c BigInt) are skipped in objects and
    become null in arrays. Returns an empty QJsonObject if \a jsObject is not
    a JS object (\nullptr, \c null, \c undefined, a primitive) or is an array
    or a function. It also returns an empty QJsonObject, logging the error and
    leaving no exception pending, if \a jsObject is nested too deeply, for
    example because it contains a reference cycle, or if a JS exception is
    raised while reading it, for example by a property getter.
 
    This is how a platform object, for example a received \c Want, is taken
    to the Qt thread.
