मान लीजिए, हमारे पास एक ऑब्जेक्ट है जिसमें कुंजियां स्ट्रिंग लिटरल हैं और उनके मान भी ऑब्जेक्ट हैं जैसे -
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'}, }हमें एक फ़ंक्शन लिखना है जो ऑब्जेक्ट को उसकी कुंजियों के अनुसार सॉर्ट करता है और उसे लौटाता है।
उदाहरण
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));आउटपुट
कंसोल में आउटपुट होगा -
{ 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' } }
