Answer 1

You can use Object.assign()

const a = [{"serverid":65,"name":"Apple"},{"serverid":98,"name":"Mac"}];
const b = [{"serverid":65,"count":2},{"serverid":98,"count":9}];
const c = a.map((obj, index) => Object.assign(obj, b[index]));

to learn more about Object.assign()

const a = [{"serverid":65,"name":"Apple"},{"serverid":98,"name":"Mac"}];
const b = [{"serverid":65,"count":2},{"serverid":98,"count":9}];
const c = a.map((obj, index) => Object.assign(obj, b[index]));

console.log(c)
