使用reduce()和Typescript解析嵌套对象

const nestedObject = {
  a: 1,
  b: {
    c: 2,
    d: {
      e: 3,
      f: {
        g: 4,
      },
    },
  },
};

function flattenObject(obj: any): any {
  return Object.keys(obj).reduce((acc, key) => {
    if (typeof obj[key] === 'object' && !Array.isArray(obj[key])) {
      const flattenedObject = flattenObject(obj[key]);
      Object.keys(flattenedObject).forEach((nestedKey) => {
        acc[`${key}.${nestedKey}`] = flattenedObject[nestedKey];
      });
    } else {
      acc[key] = obj[key];
    }
    return acc;
  }, {});
}

const flattenedObject = flattenObject(nestedObject);
console.log(flattenedObject);

{
  a: 1,
  'b.c': 2,
  'b.d.e': 3,
  'b.d.f.g': 4,
}
