javascript - 将项目推送到数组深度中的同一个嵌套子项

Question

我无法弄清楚如何将项目推送到同一个嵌套数组，例如:

var arr = ['foo', 'bar', 'buz', 'hello'];
 // It should be now look like this: 
const output = {name: 'foo', children: [
      {name: 'bar', children: [
          {name: 'buz', children: [
              {name: 'hello', children: []}
          ]}
      ]}
  ]};

Answer 1

使用reduce:

const arr = ['foo', 'bar', 'buz', 'hello'];

const result = arr.reverse().reduce((acc, val) => ({name: val, children: [acc]}), {});

console.log(result);
