    Description

      Consider the following code snippet:

          QString code(QStringLiteral(R"QBS(
            var test = ['val2'];
            test.unshift('val1');
            test = test.concat([]);
            throw(JSON.stringify(test));
    )QBS"));
    QJSEngine e;
    QJSValue v = e.evaluate(code);
    qDebug() << v.toString();

      The output is:

      "[\"val1\",null]"

      I was not able to reduce it further. The array can be initialized like above or filled with push. But it must contain something before doing unshift followed by an empty concat.
