javascript - 通过自定义键将Seq转换为Map

Question

如何将以下 JavaScript 数组转换为由列表中每个对象的“id”作为键控的 Immutable.Map？

    id: 'all',
    label: 'All',
    isSelected: false
  }, {
    id: '1',
    label: '1',
    isSelected: true
  }, {
    id: '2',
    label: '2',
    isSelected: false
  }, {
    id: '3',
    label: '3',
    isSelected: false
}]

我希望能够做到:

// {id: 'all', label: 'All', isSelected: true}

Answer 1

这可以使用如下所示的不可变 JS 来完成。

var buttons = [{
    id: 'all',
    label: 'All',
    isSelected: false
  }, {
    id: '1',
    label: '1',
    isSelected: true
  }, {
    id: '2',
    label: '2',
    isSelected: false
  }, {
    id: '3',
    label: '3',
    isSelected: false
}];

buttonImmutableList = Immutable.fromJS(buttons)
buttonImmutableMap = buttonImmutableList.reduce((a,c)=>  a.set(c.get('id'),c), Immutable.Map())
