seamless-immutable的使用问题

Question

现在有这么一段数据

let a = [{list:[1,2,3]},{list:[4,5,6]}];

let aIm = immutable(a);

我想把list数组中的每一项都加1，应该怎么写？

Answer 1

let list = Immutable.fromJS([{list:[1,2,3]},{list:[4,5,6]}])list.map(item => item.updateIn(['list'], list => list.map(n => ++n))).toJS()

Answer 2

a.map(x => {    return x.list.map(y => y+1)})

Answer 3

可以这样做，用两层reduce来实现：(() => {  let a = [{list: [1, 2, 3]}, {list: [4, 5, 6]}]  let aIm = Immutable(a)  aIm = aIm.reduce((aIm, item, index) =>    aIm.updateIn([index, 'list'], add), aIm)  function add (arr) {    return arr.reduce((arr, item, index) =>      arr.updateIn([index], plus), arr)  }  function plus (x) {    return x + 1  }  console.log(aIm)})()
