How to Filter object and get certain field in Javascript

Question

I'm struggle with using filter.

Initial object
This is my object.

[{
  isOpen : true,
  items : [
    {itemId : '', name : 'some name'},
    {itemId : 'new', name : 'new name'}
  ]
},]

Expected Result

I just want to show that the itemId is not an empty string and also isOpen field.

[{
  isOpen : true,
  items : [
    {itemId : 'new', name : 'new name'}
  ]
},]

---

What I try

  const removeEmptyStringInItems = (item) => item.items?.filter((v) => v.itemId);
  const finalItems = myItems.map(removeEmptyStringInItems);

output .

{itemId : 'new', name : 'new name'}

Any ideas for this problem? I really need help!

Answer 1

you could try update the code to this to keep the finalItems format same as the initial value

const removeEmptyStringInItems = (items = []) => items?.filter((v) => v.itemId);
const finalItems = myItems.map((v) => ({...v, items: removeEmptyStringInItems(v.items)}));
