Answer 1

You could map the wnated entries and builds objects with it.

const 
    keys = ['key_1', 'key_3'],
    data = [{ key_1: 'Some Value A', key_2: 'Some Other Value A', key_3: 'Some Final Value A' }, { key_1: 'Some Value B', key_2: 'Some Other Value B', key_3: 'Some Final Value B' }, { key_1: 'Some Value C', key_2: 'Some Other Value C', key_3: 'Some Final Value C' }],
    result = data.map(o => Object.fromEntries(keys.map(k => [k, o[k]])));

console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }
