Rename keys in an array of objects using JavaScript
I have an array of country objects. In this array I would like to replace the key name with country.
const countries = [
{"id": 1, "name": "Afghanistan"},
{"id": 2, "name": "Albania"},
{"id": 3, "name": "Algeria"},
{"id": 4, "name": "American Samoa"}
];We can use map function to manipulate the array easily.
const transformed = countries.map(function(country) {
country.country = country.name;
delete country.name;
return country;
})
console.log(transformed);
/* const countries = [
{"id": 1, "country": "Afghanistan"},
{"id": 2, "country": "Albania"},
{"id": 3, "country": "Algeria"},
{"id": 4, "country": "American Samoa"}
];
*/
