Wrong documentation for convert util function

[luisvillara]

Seems like there is a wrong documentation for the convert util function, I tried to use it and it didn't work, e.g:

const items = [
  {id: 1, parentId: null, index: 0, name: "Categories"},
  {id: 2, parentId: null, index: 1, name: "Brand"},
  {id: 3, parentId: 1, index: 0, name: "Bags"},
  {id: 4, parentId: 1, index: 1, name: "Mugs"},
  {id: 5, parentId: 1, index: 2, name: "Clothing"},
  {id: 8, parentId: 2, index: 0, name: "Ruby"},
  {id: 9, parentId: 2, index: 1, name: "Apache"},
  {id: 10, parentId: 2, index: 2, name: "Spree"},
  {id: 11, parentId: 2, index: 3, name: "Rails"}
];

const convertedItems = convert(items);

The result for convertedItems is an empty array.

Solution

The thing is that the database data must not have null as a parentId for the first level items.

The data must look something like this:

const items = [
  {id: 1, parentId: 0, index: 0, name: "Categories"},
  {id: 2, parentId: 0, index: 1, name: "Brand"},
  {id: 3, parentId: 1, index: 0, name: "Bags"},
  {id: 4, parentId: 1, index: 1, name: "Mugs"},
  {id: 5, parentId: 1, index: 2, name: "Clothing"},
  {id: 8, parentId: 2, index: 0, name: "Ruby"},
  {id: 9, parentId: 2, index: 1, name: "Apache"},
  {id: 10, parentId: 2, index: 2, name: "Spree"},
  {id: 11, parentId: 2, index: 3, name: "Rails"}
];

Thanks @luisvillara !
I updated the convert function so now it should work if the parentId of the first level items is null, 0, an empty string or even it's omit!
