javascript - Immutablejs - 更新嵌套映射和列表中的值

Question

我有这个 immutableJs map :

event: {
    days: [
        {
            date: 1,
            sessions: [
                {
                    id: 1,
                    name: 2,
                    startTime: 1,
                    endTime: 1,
                    description: 1,
                    detailsLink: 1,
                    details: {visible: true}
                },
                {
                    id: 2,
                    name: 2,
                    startTime: 2,
                    endTime: 2,
                    description: 2,
                    detailsLink: 2,
                    details: {visible: false}
                },
                {
                    id: 3,
                    name: 3,
                    startTime: 3,
                    endTime: 3,
                    description: 3,
                    detailsLink: 3,
                    details: {visible: true}
                }
            ]
        },
        {
            date: 2,
            sessions: [
                {
                    id: 1,
                    name: 2,
                    startTime: 1,
                    endTime: 1,
                    description: 1,
                    detailsLink: 1,
                    details: {visible: false}
                },
                {
                    id: 2,
                    name: 2,
                    startTime: 2,
                    endTime: 2,
                    description: 2,
                    detailsLink: 2,
                    details: {visible: false}
                },
                {
                    id: 3,
                    name: 3,
                    startTime: 3,
                    endTime: 3,
                    description: 3,
                    detailsLink: 3,
                    details: {visible: true}
                }
            ]
        }
    ]
}

我想将可见的:true 更新为visible:false。我尝试了很多不同的方法，包括过滤器、序列等，但没有运气。

关于如何使用 immutableJs 做到这一点有什么想法吗？

聚会迟到了，但是这样怎么样(假设您的数据位于名为 data 的变量中):

data.setIn(["event", "days"],
    data.getIn(["event", "days"]).map(day => 
        day.set("sessions", day.get("sessions").map(session => 
            session.setIn(['details', 'visible'], false)))
    )
)
