react redux reducer中缺少数组

Question

i am trying to check my inner array id same as dispatched id, table example

{
 _id :1,
 name: sagar elias jacky
 Amenities :[{ id: 100, title : hi },{ id: 101, title : hallo } ]
}

checking dispatched id exit or not using map,

return { ...state, 
  items : {...state.items, 
  Amenities : { ...state.items.Amenities
 .map(x=> x._id === action.dispatchedID ?  {...x,deleting: true} :  x ) }}}

but it will return with non array Amenities, like

Amenities:
0: { id: 100, title : hi },
1: { id: 101, title : hallo }

i want this to

Amenities:Array(2)
0: { id: 100, title : hi },
1: { id: 101, title : hallo }

Answer 1

When you spread an array inside {} , it creates an object with indexes of array as keys

 const array = [{a:1}, {a:2}] console.log({...array})

So, change

Amenities : { ...state.items.Amenities
 .map(x=> x._id === action.dispatchedID ?  {...x,deleting: true} :  x ) }

to:

Amenities : [ ...state.items.Amenities
 .map(x=> x._id === action.dispatchedID ?  {...x,deleting: true} :  x ) ]
