How to insert specific index in array using lodash?

Question

I already see the lodash documentation but I don't know what function do I need to use to solve my problem. I have array

const arr = [
  {name: 'john'},
  {name: 'jane'},
  {name: 'saske'},
  {name: 'jake'},
  {name: 'baki'} 
]

I want to add {name: 'ace'} before saske. I know about splice in javascript, but I want to know if this is possible in lodash.

You can try something like this:

---

const arr = [{
    name: 'john'
  },
  {
    name: 'jane'
  },
  {
    name: 'saske'
  },
  {
    name: 'jake'
  },
  {
    name: 'baki'
  }
]

const insert = (arr, index, newItem) => [
  ...arr.slice(0, index),

  newItem,

  ...arr.slice(index)
];

const newArr = insert(arr, 2, {
  name: 'ace'
});

console.log(newArr);
