How do I create a tree view with minimum updates on updating a child node.

I wrote one but when I add one node or delete a node, it updates the whole tree from scratch.

Ideally, you don't have one root node that handles the whole tree. This won't be the best

tree: {
children: [{tree: {}}]
}

tree: {
children: [{tree: {}}]
}

You should try to do something like this instead

"rootId": {
children: ["nodeId1", "nodeId2"]
}

"nodeId1":{
children: ["nodeId4", "nodeId3"]
}

"nodeId2":{
children: ["nodeId7", "nodeId8"]
}

"rootId": {
children: ["nodeId1", "nodeId2"]
}

"nodeId1":{
children: ["nodeId4", "nodeId3"]
}

"nodeId2":{
children: ["nodeId7", "nodeId8"]
}

I have this structure passed as props:

  let moves = [

    ]

So an array of paths into the tree and data separated by space. Please turn this into a renderable tree view. I have no idea how to do this.
