For example, let's say I have the following:
let data = [{name: "Bob"}, {name: "Alice"}]
let numArr = [12, 34]
I'd like this as the result:
let newData = [{name: "Bob", number: 12}, {name: "Alice", number: 34}]

Using Array#map:
const
data = [{name: "Bob"}, {name: "Alice"}],
numArr = [12, 34];
const newData = data.map((e, i) => ({ ...e, number: numArr[i] }));
console.log(newData);

You can use Symbol.iterator and forEach.
let data = [{name: "Bob"}, {name: "Alice"}];
let numArr = [12, 34];
ns=numArr[Symbol.iterator]();
data.forEach((d)=>d.number=ns.next().value);
document.write(JSON.stringify(data));You need to define the iterated array outside of the forEach loop, otherwise the definition is re-initiated with every pass, and returns the same value each time.
