如何将包含子路径数组的平面数组转换为基于路径的嵌套对象数组？

function convertArrayToNestedObject(arr) {
  const result = {};

  for (let i = 0; i < arr.length; i++) {
    const path = arr[i].split('/');
    let current = result;

    for (let j = 0; j < path.length; j++) {
      const key = path[j];

      if (!current[key]) {
        current[key] = {};
      }

      current = current[key];
    }
  }

  return result;
}

const flatArray = [
  'a/b/c',
  'a/b/d',
  'a/e',
  'f',
  'g/h/i/j',
];

const nestedObject = convertArrayToNestedObject(flatArray);
console.log(nestedObject);

{
  a: {
    b: {
      c: {},
      d: {}
    },
    e: {}
  },
  f: {},
  g: {
    h: {
      i: {
        j: {}
      }
    }
  }
}
