Function.prototype.call() on undefined results in error

    XMLWordPrintable

Details

    Description

          QJSEngine engine;
    QJSValue result = engine.evaluate(QStringLiteral("Array.prototype.map.call(undefined, function (a) {return a; } );"));
    qDebug() << result.toString();

      Results in 

      "TypeError: Value is undefined and could not be converted to an object"

      I believe that this is not correct. The expected behavior is that an undefined this parameter is converted to the global object unless strict mode is enabled.
