Such data cannot generate a tree

var dataOne = [
{
id: 100,
name: 'Portfolio',
parent_id: undefined
},
{
id: 200,
name: 'Web Development',
parent_id: 100
},
{
id: 300,
name: 'Recent Works',
parent_id: 200
},
{
id: 400,
name: 'About Me',
parent_id: undefined
}
];

I build trees of objects that shouldn't be cloned, because I want to keep reference. Moreover, cloning messes up my objects that have custom serialization functions.
I will stick to version 3.1.0 until this problem is addressed.

you just change the passed array by add children property, and the array has been changed forever.

I mean you can't change the arguments passed in, you should keep the function is pureable

this bug is horibble. Can you fix it as soon as posibble.

When data had 2 or more top levels 'root' there is stack overflow occured.
Here is representation:

Just remove top root level and all works fine.

hi guys, he's the issue I'm facing using parentProperty options.

var data2 =[
{
id: 1,
created_at: '2020-05-09T16:13:04.896Z',
folder_id: 1,
'Filess.name': 'MyFirstLesson'
},
{
id: 2,
created_at: '2020-05-11T16:13:04.896Z',
folder_id: 2,
'Filess.name': 'MyFirstLesson'
},
{
id: 3,
created_at: '2020-05-11T16:13:04.896Z',
folder_id: 3,
'Filess.name': 'MyFirstLesson'
},
{
id: 4,
created_at: '2020-05-09T16:13:04.896Z',
folder_id: 1,
'Filess.name': 'Meeting1'
},
{
id: 5,
created_at: '2020-05-16T16:13:04.896Z',
folder_id: 1,
'Filess.name': 'SetupRoom'
},
{
id: 6,
created_at: '2020-05-17T16:13:04.896Z',
folder_id: 1,
'Filess.name': 'SetupRoom'
},
{
id: 7,
created_at: '2020-05-17T16:13:04.896Z',
folder_id: 1,
'Filess.name': 'SetupRoom'
},
{
id: 8,
created_at: '2020-05-20T15:26:36.656Z',
folder_id: 1,
'Filess.name': 'Annotation 2020-04-08 135240.jpg'
}
]

arrayToTree(data2, {parentProperty: 'folder_id})

returns empty array

arrayToTree(dataTwo, {
  parentProperty: 'parent',
  customID: '_id',
 each:(node)=>{
// here i can �do some things. like choice  the right node to an other list
}
});

this options we can choice some node but no need to deep traverse the whole tree.

How can I import this module in Angular2 app and use it there ?

Here is my problem in details:

I've been trying to get this to work with a nested parent_id but I can't seem to find the solution.

Say I have:

[
    {
      "id": "1",
      "attributes": {
        "name": "Parent",
        "parent_id": null,
      }
    },
    {
      "id": "2",
      "attributes": {
        "name": "Child One",
        "parent_id": 1,
      }
    },
    {
      "id": "3",
      "attributes": {
        "name": "Child Two",
        "parent_id": 1,
      }
    },
]

Will arrayToTree() work in this situation?

ArrayToTree returns incorrect array. Last element is function.

thankyou
