How to convert a specified JSON object value to an array

Question

So imagine having a JSON file like:

[
  { "name": "David", "code": "DA" },
  { "name": "Solomon", "code": "SO" },
  { "name": "Mirage", "code": "MI" }
]

How can I convert it to something like this: ['David', 'Solomon', 'Mirage']and ['DA', 'SO', 'MI]

a.map(item => item['name']) and a.map(item => item['code']) — iamhuynq

let data = [
 { "name": "David", "code": "DA" },
 { "name": "Solomon", "code": "SO" },
 { "name": "Mirage", "code": "MI" }
];

 const result = data.map(item => item.name);
 const result2 = data.map(item => item.code);

 console.log(result, result2);

If you do not wish to return value, use .forEach instead. .map returns n length array
