在javascript中将` `JSON `映射为`tree`

function mapJSONToTree(json) {
  const tree = {};

  function traverse(obj, parentKey) {
    for (let key in obj) {
      if (obj.hasOwnProperty(key)) {
        const value = obj[key];
        const node = {};

        if (typeof value === 'object' && value !== null) {
          node.children = [];
          traverse(value, key);
        } else {
          node.value = value;
        }

        if (parentKey) {
          tree[parentKey].children.push({ [key]: node });
        } else {
          tree[key] = node;
        }
      }
    }
  }

  traverse(JSON.parse(json), null);

  return tree;
}

const json = '{"name": "John", "age": 30, "children": [{"name": "Alice", "age": 5}, {"name": "Bob", "age": 8}]}';
const tree = mapJSONToTree(json);
console.log(tree);
