키 값으로 객체의 객체를 정렬하는 방법 JavaScript

키를 문자열 리터럴로, 그 값을 객체로 가진 객체가 다음과 같이 있다고 가정해 보겠습니다. -

const companies = {
   'landwaves ltd': {employees: 1200, worth: '1.2m', CEO: 'Rajiv Bansal'},
   'colin & co': {employees: 200, worth: '0.2m', CEO: 'Sukesh Maheshwari'},
   'motilal biscuits': {employees: 975, worth: '1m', CEO: 'Rahul Gupta'},
   'numbtree': {employees: 1500, worth: '1.5m', CEO: 'Jay Kumar'},
   'solace pvt ltd': {employees: 1800, worth: '1.65m', CEO: 'Arvind Sangal'},
   'ambicure': {employees: 170, worth: '0.1m', CEO: 'Preetam Chawla'},
   'dis n dat': {employees: 540, worth: '1m', CEO: 'Mohit Sharma'},
}

키에 따라 개체를 정렬하고 반환하는 함수를 작성해야 합니다.

예시

const companies = {
   'landwaves ltd': {employees: 1200, worth: '1.2m', CEO: 'Rajiv Bansal'},
   'colin & co': {employees: 200, worth: '0.2m', CEO: 'Sukesh Maheshwari'},
   'motilal biscuits': {employees: 975, worth: '1m', CEO: 'Rahul Gupta'},
   'numbtree': {employees: 1500, worth: '1.5m', CEO: 'Jay Kumar'},
   'solace pvt ltd': {employees: 1800, worth: '1.65m', CEO: 'Arvind Sangal'},
   'ambicure': {employees: 170, worth: '0.1m', CEO: 'Preetam Chawla'},
   'dis n dat': {employees: 540, worth: '1m', CEO: 'Mohit Sharma'},
};
const sortKeys = (obj) => {
   return Object.assign(...Object.entries(obj).sort().map(([key, value])
   => {
      return {
         [key]: value
      }
   }));
};
console.log(sortKeys(companies));

출력

콘솔의 출력은 다음과 같습니다. -

{
   ambicure: { employees: 170, worth: '0.1m', CEO: 'Preetam Chawla' },
   'colin & co': { employees: 200, worth: '0.2m', CEO: 'Sukesh Maheshwari'},
   'dis n dat': { employees: 540, worth: '1m', CEO: 'Mohit Sharma' },
   'landwaves ltd': { employees: 1200, worth: '1.2m', CEO: 'Rajiv Bansal' },
   'motilal biscuits': { employees: 975, worth: '1m', CEO: 'Rahul Gupta' },
   numbtree: { employees: 1500, worth: '1.5m', CEO: 'Jay Kumar' },
   'solace pvt ltd': { employees: 1800, worth: '1.65m', CEO: 'Arvind Sangal'
   }
}
