  • You do not need `addPersn.push`. You can directly push it to `persons`. However, assuming you are trying to create a setter, you can do this: `addPerson = (newPerson) => person.push(newPerson)` – Rajesh Nov 28 '22 at 09:30
  • [`push`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/push) returns the new length of the array. – Lain Nov 28 '22 at 09:33
  • At step `persons.push(addPerson)` you are pushing an array with one person details `addPerson` in `persons` array. Thus at the end `persons` array will have `[Person, Person, [Person]]` that last element is not object but an array with one object. Instead directly push the object in `persons` array. Do like this. `let newPerson = { "person1": "person2" }` , then, `persons.push(newPerson)` – sachuverma Nov 28 '22 at 09:35

Try this

let persons = [
  {
    person1: "person1",
  },
  {
    person2: "person2",
  },
];

const newPerson = {
    person3: "person3",
}

persons.push(newPerson);
console.log(persons);
