javascript - Object array clone with subset of properties

Question

What is the most efficient way in JavaScript to clone an array of uniform objects into one with a subset of properties for each object?

UPDATE

Would this be the most efficient way to do it or is there a better way? -

var source = [
    {
        id: 1,
        name: 'one',
        value: 12.34
    },
    {
        id: 2,
        name: 'two',
        value: 17.05
    }
];

// copy just 'id' and 'name', ignore 'value':
var dest = source.map(function (obj) {
    return {
        id: obj.id,
        name: obj.name
    };
});

Answer 1

using Object Destructuring and Property Shorthand

let array = [{ a: 5, b: 6, c: 7 }, { a: 8, b: 9, c: 10 }];
let cloned = array.map(({ a, c }) => ({ a, c }));

console.log(cloned); // [{ a: 5, c: 7 }, { a: 8, c: 10 }]
