    Symbol.iterator & object-rest-spread

what's this exactly mean?

 ...createLoading({obj})

Is it ES6 destructuring assignment?

// 1. Initialize
const app = dva(
    {
        ...createLoading(
            {
                effects: true
            }
        ),
        history: browserHistory,
        onError(error) {
            message.error(error.message);
        }
    }
);
