从属性名称和值的数组构建嵌套对象的数组

function buildNestedObjectsFromArray(array) {
  const result = [];

  for (const item of array) {
    const keys = item.name.split('.');
    let temp = {};

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

      if (!temp[key]) {
        temp[key] = {};
      } else if (typeof temp[key] !== 'object') {
        temp[key] = {};
      }

      if (i === keys.length - 1) {
        temp[key] = item.value;
      }

      temp = temp[key];
    }

    result.push(temp);
  }

  return result;
}

// 示例用法
const array = [
  { name: 'a.b.c', value: 1 },
  { name: 'a.b.d', value: 2 },
  { name: 'a.e', value: 3 },
  { name: 'f', value: 4 }
];

const nestedObjects = buildNestedObjectsFromArray(array);
console.log(nestedObjects);

[
  { a: { b: { c: 1, d: 2 }, e: 3 }, f: 4 }
]
