Javascript 如何使用 node 索引从树数据 struct 创建平面数组

const TREE_DATA = [{
    name: 'USA',
    children: [{
        name: 'Texas',
        children: [{
            name: 'Dallas'
        }, {
            name: 'Houston'
        }]
    }, {
        name: 'California',
        children: [{
            name: 'Los Angeles'
        }, {
            name: 'San Francisco'
        }]
    }, {
        name: 'New York',
        children: [{
            name: 'New York City'
        }, {
            name: 'Buffalo'
        }]
    }],
}, {
    name: 'India',
    children: [{
        name: 'Bihar',
        children: [{
            name: 'Patna'
        }, {
            name: 'Gaya'
        }],
    }],
}, ];

let treeDataGroupedBy = ['Country', 'State', 'City'];
let treeNodeInput = ['0-0-0', '1-0-1'];
let data = []; /*Expected Result [{
    Country: 'USA',
    State: 'Texas',
    City: 'Dallas'
}, {
    Country: 'India',
    State: 'Bihar',
    City: 'Gaya'
}]*/

for (let item of treeNodeInput) {
    let nodesArray = item.split("-");
    let count = 0;
    let rowObj = {};
    let child = TREE_DATA
    for (let node of nodesArray) {
            if(child.hasOwnProperty('children')){
                child =child["children"][node]
            }
            else{
                child =child[node]
            }
                rowObj[treeDataGroupedBy[count]] = child.name;
                count++;
      
    }
    data.push(rowObj);
}

console.log(data)
