Adding elements to multidimensional arrays in JavaScript

Suppose we have such an array with users:

javascriptlet users = [
  {
    name: 'name1',
    surn: 'surn1',
  },
  {
    name: 'name2',
    surn: 'surn2',
  },
  {
    name: 'name3',
    surn: 'surn3',
  },
];

Let's add one more user to this array. To do this, as a parameter of the push method, we will pass a new object with a user:

javascriptusers.push({
  name: 'name4',
  surn: 'surn4',
});

javascriptlet employees = [
  {
    name: 'name1',
    salary: 300,
    age: 28,
  },
  {
    name: 'name2',
    salary: 400,
    age: 29,
  },
  {
    name: 'name3',
    salary: 500,
    age: 30,
  },
];
