javascript - 如何用大括号(包括子数组)包裹 json 的值？

Question

基于这篇文章How can I wrap the value of json with curly braces?

在嵌套结构中附加“值”怎么样？

{ name: 'Bill', lastname: 'Smith', child: { name: 'Adam', options: [{ option: "1" }, { option: "2" }] } }

结果应该是

{ name: { value:'Bill'}, lastname: { value:'Smith'},
  child: {
        name: { value:'Adam'},
        options: [{
                  option: { value:'1'}
                 },
                 { option: { value:'2'}
                 }]
        }
        ... 
}

递归地运行它并为数组和对象添加特殊处理。

const input = { name: 'Bill', lastname: 'Smith', child: { name: 'Adam', options: [{ option: "1" }, { option: "2" }] } };
const transform = (input) => Object.fromEntries(
  Object.entries(input).map(([key, value]) => {
    // If it is an array, transform each object in it
    if(Array.isArray(value)) {
      return ([key, value.map(el => transform(el))]); 
    } 
    // If it is an object, transform its value
    else if(typeof value === 'object' && value !== null)  {
      return [key, transform(value)]; 
    }
    // If it is a normal value, add the {value: } part
    else {
      return ([key, { value }]); 
    }
  })
);

console.log(transform(input));
