小编Man*_*hen的帖子

这是代码,

export function createConnect({
    connectHOC = connectAdvanced,
    mapStateToPropsFactories = defaultMapStateToPropsFactories,
    mapDispatchToPropsFactories = defaultMapDispatchToPropsFactories,
    mergePropsFactories = defaultMergePropsFactories,
    selectorFactory = defaultSelectorFactory
} = {}) {...}

什么{connectHOC = connectAdvanced ...} = {}意味着在函数参数声明中？

我知道

= {}

可能意味着函数参数的默认值,但是前面括号内代码的用法是什么？
