Answer 1

Short way with array reduce:

const arrayOfObjects = [
 {name: "name1", surname: "surname1"}, {name: 'Anne', surname: 'Example'}, {name: 'name3', surname: 'Example3'}
];
/*
{name: ['Fred', 'Anne'], surname: ['Example', 'Shultz']}
*/
var result = arrayOfObjects.reduce((obj,current)=>{
    (obj['name'] = obj['name']||[]).push(current.name);
    (obj['surname'] = obj['surname']||[]).push(current.surname);
    return obj;
},{});
console.log(result);
