将树数据转换为对象

Question

嗨，我一直在致力于将树转换为对象。我知道如何递归获取整个树，但是我不知道将json ['name']和json ['children']放置在何处，并达到预期的结果。有没有人可以给我提示？

谢谢您的帮助。

# Here is the tree structure that is created by tree-model.min.js

#Input:
/*
tree = Node{
    config: {childrenPropertyName: "children", modelComparatorFn: undefined}
    model: {"name": str_1, "children": [Node, ..., Node]}
    children: [Node, Node, ..., Node]
}
*/

#Expected outcome:
/*
{name: str_1, children: [
    {name: str_2, children: [...]}, 
    {name: str_3, children: [...]}
]}
*/


# Here is what I have tried
function treeToJSON(tree, json){
    console.log(tree.model.name)
    console.log(json)
    if(tree.hasChildren()){
	    json['name'] = tree.model.name;

	    (tree.children).forEach(function(_tree){
		    if(!json['children']){
			    json['children'] = []	
		    }
		    json['children'].push({'name': _tree.model.name})			
		    return treeToJSON(_tree, json)			
	    })
    } 
    else{
	    json['name'] =tree.model.name
	    return json
    }
}


treeToJSON(tree, {})
