I have the following array, for example:
[{id:1},{id:2}{id:3},{id:4},{id:5},...{id:20}]
May I ask how to generate a JSON object as below in order to achieve the following tree in Image 1? It does not need a parent id as it is first come first serve and each node will only have direct 3 childs.
I think it will run through a function and append the children to the object. Also I wish to control the number of childrens in the future too. Thanks in advance
JSON object
{
"tree": {
"id": 1,
"children": [
{
"id": 2,
"children": [
{
"id": 5,
"children": [
{
"id": 11
},
{
"id": 12
},
{
"id": 13
}
]
},
{
"id": 6
},
{
"id": 7
}
]
},
{
"id": 3,
"children": [
{
"id": 8
},
{
"id": 9
},
{
"id": 10
}
]
},
{
"id": 4,
"children": [
{
"id": 11
},
{
"id": 12
},
{
"id": 13
}
]
}
]
}
}
