In this example, we create a QScriptEngine and evaluate a JavaScript array using the engine. Then we call `isArray` on the resulting QScriptValue, which returns `true` because the value is indeed an array. Example 2:cpp QScriptEngine engine; QScriptValue object = engine.evaluate("{name: 'John', age: 30}"); bool isArray = object.isArray(); // false ``` In this example, we create a QScriptEngine and evaluate a JavaScript object using the engine.
