问如果匹配，如何比较两个json对象，返回这些值？

EN

const main = () => {
  const currentUser = {
    subAccount: {
      setup: true,
      edit: true,
      delete: true
    },
  };
  
  const parentUser = {
    subAccount: {
      setup: true,
      edit: true,
    },
    game: {
      edit: true
    }
  }
  const result = compareTwoObj(currentUser, parentUser);
  // print the result;
  console.log('result====>', JSON.stringify(result));
}


const compareTwoObj = (obj1, obj2) => {
  const common = {};
  for (const key of Object.keys(obj2)) {
      if (obj2[key] !== undefined) {
          if (typeof obj1[key] === 'object') {
              common[key] = compareTwoObj(obj1[key], obj2[key]);
          }
          else {

                  common[key] = obj1[key];
              }
          }
      }
  }
  return common;
}

main();

function compare(current, parent) {
    let result = {};
    for (let key of Object.keys(parent)) {
        if (parent[key] != undefined) {
            if (typeof current[key] == "object") {
                result[key] = compare(current[key], parent[key]);
            }
            else {
                if (current[key] == parent[key]) {
